 @mansect description
 Most of the main utilities are able to write their log files to a Unix
 Domain socket if configured that way.  @command{watchgnupg} is a simple
 listener for such a socket.  It ameliorates the output with a time stamp
 and makes sure that long lines are not interspersed with log output from
 other utilities.  This tool is not available for Windows.
 
 
 @noindent
 @command{watchgnupg} is commonly invoked as
 
 @example
 watchgnupg --force $(gpgconf --list-dirs socketdir)/S.log
 @end example
 @manpause
 
 @noindent
 This starts it on the current terminal for listening on the standard
 logging socket (which is either @file{~/.gnupg/S.log} or
 @file{/var/run/user/UID/gnupg/S.log}).
 
 @mansect options
 @noindent
 @command{watchgnupg} understands these options:
 
 @table @gnupgtabopt
 
 @item --force
 @opindex force
 Delete an already existing socket file.
 
 @anchor{option watchgnupg --tcp}
 @item --tcp @var{n}
 Instead of reading from a local socket, listen for connects on TCP port
 @var{n}.
 
 @item --time-only
 @opindex time-only
 Do not print the date part of the timestamp.
 
 @item --verbose
 @opindex verbose
 Enable extra informational output.
 
 @item --version
 @opindex version
 Print version of the program and exit.
 
 @item --help
 @opindex help
 Display a brief help page and exit.
 
 @end table
 
 @noindent
 @mansect examples
 @chapheading Examples
 
 @example
 $ watchgnupg --force --time-only $(gpgconf --list-dirs socketdir)/S.log
 @end example
 
 This waits for connections on the local socket
 (e.g. @file{/home/foo/.gnupg/S.log}) and shows all log entries.  To
 make this work the option @option{log-file} needs to be used with all
 modules which logs are to be shown.  The suggested entry for the
 configuration files is:
 
 @example
 log-file socket://
 @end example
 
 If the default socket as given above and returned by "echo $(gpgconf
 --list-dirs socketdir)/S.log" is not desired an arbitrary socket name
 can be specified, for example @file{socket:///home/foo/bar/mysocket}.
 For debugging purposes it is also possible to do remote logging.  Take
 care if you use this feature because the information is send in the
 clear over the network.  Use this syntax in the conf files:
 
 @example
 log-file tcp://192.168.1.1:4711
 @end example
 
 You may use any port and not just 4711 as shown above; only IP
 addresses are supported (v4 and v6) and no host names.  You need to
 start @command{watchgnupg} with the @option{tcp} option.  Note that
 under Windows the registry entry
 @var{HKCU\Software\GNU\GnuPG:DefaultLogFile} can be used to change the
 default log output from @code{stderr} to whatever is given by that
 entry.  However the only useful entry is a TCP name for remote
 debugging.

 @mansect description
 The @command{gpgconf} is a utility to automatically and reasonable
 safely query and modify configuration files in the @file{.gnupg} home
 directory.  It is designed not to be invoked manually by the user, but
 automatically by graphical user interfaces (GUI).@footnote{Please note
 that currently no locking is done, so concurrent access should be
 avoided.  There are some precautions to avoid corruption with
 concurrent usage, but results may be inconsistent and some changes may
 get lost.  The stateless design makes it difficult to provide more
 guarantees.}
 
 @command{gpgconf} provides access to the configuration of one or more
 components of the GnuPG system.  These components correspond more or
 less to the programs that exist in the GnuPG framework, like GPG,
 GPGSM, DirMngr, etc.  But this is not a strict one-to-one
 relationship.  Not all configuration options are available through
 @command{gpgconf}.  @command{gpgconf} provides a generic and abstract
 method to access the most important configuration options that can
 feasibly be controlled via such a mechanism.
 
 @command{gpgconf} can be used to gather and change the options
 available in each component, and can also provide their default
 values.  @command{gpgconf} will give detailed type information that
 can be used to restrict the user's input without making an attempt to
 commit the changes.
 
 @command{gpgconf} provides the backend of a configuration editor.  The
 configuration editor would usually be a graphical user interface
 program that displays the current options, their default
 values, and allows the user to make changes to the options.  These
 changes can then be made active with @command{gpgconf} again.  Such a
 program that uses @command{gpgconf} in this way will be called GUI
 throughout this section.

 @subsection Invoking gpgconf
 
 @mansect commands
 One of the following commands must be given:
 
 @table @gnupgtabopt
 
 @item --list-components
 List all components.  This is the default command used if none is
 specified.
 
 @item --check-programs
 List all available backend programs and test whether they are runnable.
 
 @item --list-options @var{component}
 List all options of the component @var{component}.
 
 @item --change-options @var{component}
 Change the options of the component @var{component}.
 
 @item --check-options @var{component}
 Check the options for the component @var{component}.
 
 @item --apply-profile @var{file}
 Apply the configuration settings listed in @var{file} to the
 configuration files.  If @var{file} has no suffix and no slashes the
 command first tries to read a file with the suffix @code{.prf} from
 the data directory (@code{gpgconf --list-dirs datadir}) before it
 reads the file verbatim.  A profile is divided into sections using the
 bracketed  component name.  Each section then lists the option which
 shall go into the respective configuration file.
 
 @item --apply-defaults
 Update all configuration files with values taken from the global
 configuration file (usually @file{/etc/gnupg/gpgconf.conf}).
 
 @item --list-dirs [@var{names}]
 Lists the directories used by @command{gpgconf}.  One directory is
 listed per line, and each line consists of a colon-separated list where
 the first field names the directory type (for example @code{sysconfdir})
 and the second field contains the percent-escaped directory.  Although
 they are not directories, the socket file names used by
 @command{gpg-agent} and @command{dirmngr} are printed as well.  Note
 that the socket file names and the @code{homedir} lines are the default
 names and they may be overridden by command line switches.  If
 @var{names} are given only the directories or file names specified by
 the list names are printed without any escaping.
 
 @item --list-config [@var{filename}]
 List the global configuration file in a colon separated format.  If
 @var{filename} is given, check that file instead.
 
 @item --check-config [@var{filename}]
 Run a syntax check on the global configuration file.  If @var{filename}
 is given, check that file instead.
 
 
 @item --query-swdb @var{package_name} [@var{version_string}]
 Returns the current version for @var{package_name} and if
 @var{version_string} is given also an indicator on whether an update
 is available.  The actual file with the software version is
 automatically downloaded and checked by @command{dirmngr}.
 @command{dirmngr} uses a thresholds to avoid download the file too
 often and it does this by default only if it can be done via Tor.  To
 force an update of that file this command can be used:
 
 @example
        gpg-connect-agent --dirmngr 'loadswdb --force' /bye
 @end example
 
 
 @item --reload [@var{component}]
 @opindex reload
 Reload all or the given component. This is basically the same as
 sending a SIGHUP to the component.  Components which don't support
 reloading are ignored.  Without @var{component} or by using "all" for
 @var{component} all components which are daemons are reloaded.
 
 @item --launch [@var{component}]
 @opindex launch
 If the @var{component} is not already running, start it.
 @command{component} must be a daemon.  This is in general not required
 because the system starts these daemons as needed.  However, external
 software making direct use of @command{gpg-agent} or @command{dirmngr}
 may use this command to ensure that they are started.  Using "all" for
 @var{component} launches all components which are daemons.
 
 @item --kill [@var{component}]
 @opindex kill
 Kill the given component that runs as a daemon, including
 @command{gpg-agent}, @command{dirmngr}, and @command{scdaemon}.  A
 @command{component} which does not run as a daemon will be ignored.
 Using "all" for @var{component} kills all components running as
 daemons.  Note that as of now reload and kill have the same effect for
 @command{scdaemon}.
 
 @item --create-socketdir
 @opindex create-socketdir
 Create a directory for sockets below /run/user or /var/run/user.  This
 is command is only required if a non default home directory is used
 and the /run based sockets shall be used.  For the default home
 directory GnUPG creates a directory on the fly.
 
 @item --remove-socketdir
 @opindex remove-socketdir
 Remove a directory created with command @option{--create-socketdir}.
 
 @end table
 
 
 @mansect options
 
 The following options may be used:
 
 @table @gnupgtabopt
 
 @item -o @var{file}
 @itemx --output @var{file}
 Write output to @var{file}.  Default is to write to stdout.
 
 @item -v
 @itemx --verbose
 Outputs additional information while running.  Specifically, this
 extends numerical field values by human-readable descriptions.
 
 @item -q
 @itemx --quiet
 @opindex quiet
 Try to be as quiet as possible.
 
 @include opt-homedir.texi
 
 @item -n
 @itemx --dry-run
 Do not actually change anything.  This is currently only implemented
 for @code{--change-options} and can be used for testing purposes.
 
 @item -r
 @itemx --runtime
 Only used together with @code{--change-options}.  If one of the
 modified options can be changed in a running daemon process, signal
 the running daemon to ask it to reparse its configuration file after
 changing.
 
 This means that the changes will take effect at run-time, as far as
 this is possible.  Otherwise, they will take effect at the next start
 of the respective backend programs.
 
 @item --status-fd @var{n}
 @opindex status-fd
 Write special status strings to the file descriptor @var{n}.  This
 program returns the status messages SUCCESS or FAILURE which are
 helpful when the caller uses a double fork approach and can't easily
 get the return code of the process.
 
 @manpause
 @end table
 
 
 @node Format conventions
 @subsection Format conventions
 
 Some lines in the output of @command{gpgconf} contain a list of
 colon-separated fields.  The following conventions apply:
 
 @itemize @bullet
 @item
 The GUI program is required to strip off trailing newline and/or
 carriage return characters from the output.
 
 @item
 @command{gpgconf} will never leave out fields.  If a certain version
 provides a certain field, this field will always be present in all
 @command{gpgconf} versions from that time on.
 
 @item
 Future versions of @command{gpgconf} might append fields to the list.
 New fields will always be separated from the previously last field by
 a colon separator.  The GUI should be prepared to parse the last field
 it knows about up until a colon or end of line.
 
 @item
 Not all fields are defined under all conditions.  You are required to
 ignore the content of undefined fields.
 @end itemize
 
 There are several standard types for the content of a field:
 
 @table @asis
 @item verbatim
 Some fields contain strings that are not escaped in any way.  Such
 fields are described to be used @emph{verbatim}.  These fields will
 never contain a colon character (for obvious reasons).  No de-escaping
 or other formatting is required to use the field content.  This is for
 easy parsing of the output, when it is known that the content can
 never contain any special characters.
 
 @item percent-escaped
 Some fields contain strings that are described to be
 @emph{percent-escaped}.  Such strings need to be de-escaped before
 their content can be presented to the user.  A percent-escaped string
 is de-escaped by replacing all occurrences of @code{%XY} by the byte
 that has the hexadecimal value @code{XY}.  @code{X} and @code{Y} are
 from the set @code{0-9a-f}.
 
 @item localized
 Some fields contain strings that are described to be @emph{localized}.
 Such strings are translated to the active language and formatted in
 the active character set.
 
 @item @w{unsigned number}
 Some fields contain an @emph{unsigned number}.  This number will
 always fit into a 32-bit unsigned integer variable.  The number may be
 followed by a space, followed by a human readable description of that
 value (if the verbose option is used).  You should ignore everything
 in the field that follows the number.
 
 @item @w{signed number}
 Some fields contain a @emph{signed number}.  This number will always
 fit into a 32-bit signed integer variable.  The number may be followed
 by a space, followed by a human readable description of that value (if
 the verbose option is used).  You should ignore everything in the
 field that follows the number.
 
 @item @w{boolean value}
 Some fields contain a @emph{boolean value}.  This is a number with
 either the value 0 or 1.  The number may be followed by a space,
 followed by a human readable description of that value (if the verbose
 option is used).  You should ignore everything in the field that follows
 the number; checking just the first character is sufficient in this
 case.
 
 @item option
 Some fields contain an @emph{option} argument.  The format of an
 option argument depends on the type of the option and on some flags:
 
 @table @asis
 @item no argument
 The simplest case is that the option does not take an argument at all
 (@var{type} @code{0}).  Then the option argument is an unsigned number
 that specifies how often the option occurs.  If the @code{list} flag
 is not set, then the only valid number is @code{1}.  Options that do
 not take an argument never have the @code{default} or @code{optional
 arg} flag set.
 
 @item number
 If the option takes a number argument (@var{alt-type} is @code{2} or
 @code{3}), and it can only occur once (@code{list} flag is not set),
 then the option argument is either empty (only allowed if the argument
 is optional), or it is a number.  A number is a string that begins
 with an optional minus character, followed by one or more digits.  The
 number must fit into an integer variable (unsigned or signed,
 depending on @var{alt-type}).
 
 @item number list
 If the option takes a number argument and it can occur more than once,
 then the option argument is either empty, or it is a comma-separated
 list of numbers as described above.
 
 @item string
 If the option takes a string argument (@var{alt-type} is 1), and it
 can only occur once (@code{list} flag is not set) then the option
 argument is either empty (only allowed if the argument is optional),
 or it starts with a double quote character (@code{"}) followed by a
 percent-escaped string that is the argument value.  Note that there is
 only a leading double quote character, no trailing one.  The double
 quote character is only needed to be able to differentiate between no
 value and the empty string as value.
 
 @item string list
 If the option takes a string argument and it can occur more than once,
 then the option argument is either empty, or it is a comma-separated
 list of string arguments as described above.
 @end table
 @end table
 
 The active language and character set are currently determined from
 the locale environment of the @command{gpgconf} program.
 
 @c FIXME: Document the active language and active character set.  Allow
 @c to change it via the command line?
 
 
 @mansect usage
 @node Listing components
 @subsection Listing components
 
 The command @code{--list-components} will list all components that can
 be configured with @command{gpgconf}.  Usually, one component will
 correspond to one GnuPG-related program and contain the options of
 that program's configuration file that can be modified using
 @command{gpgconf}.  However, this is not necessarily the case.  A
 component might also be a group of selected options from several
 programs, or contain entirely virtual options that have a special
 effect rather than changing exactly one option in one configuration
 file.
 
 A component is a set of configuration options that semantically belong
 together.  Furthermore, several changes to a component can be made in
 an atomic way with a single operation.  The GUI could for example
 provide a menu with one entry for each component, or a window with one
 tabulator sheet per component.
 
 The command @code{--list-components} lists all available
 components, one per line.  The format of each line is:
 
 @code{@var{name}:@var{description}:@var{pgmname}:}
 
 @table @var
 @item name
 This field contains a name tag of the component.  The name tag is used
 to specify the component in all communication with @command{gpgconf}.
 The name tag is to be used @emph{verbatim}.  It is thus not in any
 escaped format.
 
 @item description
 The @emph{string} in this field contains a human-readable description
 of the component.  It can be displayed to the user of the GUI for
 informational purposes.  It is @emph{percent-escaped} and
 @emph{localized}.
 
 @item pgmname
 The @emph{string} in this field contains the absolute name of the
 program's file.  It can be used to unambiguously invoke that program.
 It is @emph{percent-escaped}.
 @end table
 
 Example:
 @example
 $ gpgconf --list-components
 gpg:GPG for OpenPGP:/usr/local/bin/gpg2:
 gpg-agent:GPG Agent:/usr/local/bin/gpg-agent:
 scdaemon:Smartcard Daemon:/usr/local/bin/scdaemon:
 gpgsm:GPG for S/MIME:/usr/local/bin/gpgsm:
 dirmngr:Directory Manager:/usr/local/bin/dirmngr:
 @end example
 
 
 
 @node Checking programs
 @subsection Checking programs
 
 The command @code{--check-programs} is similar to
 @code{--list-components} but works on backend programs and not on
 components.  It runs each program to test whether it is installed and
 runnable.  This also includes a syntax check of all config file options
 of the program.
 
 The command @code{--check-programs} lists all available
 programs, one per line.  The format of each line is:
 
 @code{@var{name}:@var{description}:@var{pgmname}:@var{avail}:@var{okay}:@var{cfgfile}:@var{line}:@var{error}:}
 
 @table @var
 @item name
 This field contains a name tag of the program which is identical to the
 name of the component.  The name tag is to be used @emph{verbatim}.  It
 is thus not in any escaped format.  This field may be empty to indicate
 a continuation of error descriptions for the last name.  The description
 and pgmname fields are then also empty.
 
 @item description
 The @emph{string} in this field contains a human-readable description
 of the component.  It can be displayed to the user of the GUI for
 informational purposes.  It is @emph{percent-escaped} and
 @emph{localized}.
 
 @item pgmname
 The @emph{string} in this field contains the absolute name of the
 program's file.  It can be used to unambiguously invoke that program.
 It is @emph{percent-escaped}.
 
 @item avail
 The @emph{boolean value} in this field indicates whether the program is
 installed and runnable.
 
 @item okay
 The @emph{boolean value} in this field indicates whether the program's
 config file is syntactically okay.
 
 @item cfgfile
 If an error occurred in the configuration file (as indicated by a false
 value in the field @code{okay}), this field has the name of the failing
 configuration file.  It is @emph{percent-escaped}.
 
 @item line
 If an error occurred in the configuration file, this field has the line
 number of the failing statement in the configuration file.
 It is an @emph{unsigned number}.
 
 @item error
 If an error occurred in the configuration file, this field has the error
 text of the failing statement in the configuration file.  It is
 @emph{percent-escaped} and @emph{localized}.
 
 @end table
 
 @noindent
 In the following example the @command{dirmngr} is not runnable and the
 configuration file of @command{scdaemon} is not okay.
 
 @example
 $ gpgconf --check-programs
 gpg:GPG for OpenPGP:/usr/local/bin/gpg2:1:1:
 gpg-agent:GPG Agent:/usr/local/bin/gpg-agent:1:1:
 scdaemon:Smartcard Daemon:/usr/local/bin/scdaemon:1:0:
 gpgsm:GPG for S/MIME:/usr/local/bin/gpgsm:1:1:
 dirmngr:Directory Manager:/usr/local/bin/dirmngr:0:0:
 @end example
 
 @noindent
 The command @w{@code{--check-options @var{component}}} will verify the
 configuration file in the same manner as @code{--check-programs}, but
 only for the component @var{component}.
 
 
 @node Listing options
 @subsection Listing options
 
 Every component contains one or more options.  Options may be gathered
 into option groups to allow the GUI to give visual hints to the user
 about which options are related.
 
 The command @code{@w{--list-options @var{component}}} lists
 all options (and the groups they belong to) in the component
 @var{component}, one per line.  @var{component} must be the string in
 the field @var{name} in the output of the @code{--list-components}
 command.
 
 There is one line for each option and each group.  First come all
 options that are not in any group.  Then comes a line describing a
 group.  Then come all options that belong into each group.  Then comes
 the next group and so on.  There does not need to be any group (and in
 this case the output will stop after the last non-grouped option).
 
 The format of each line is:
 
 @code{@var{name}:@var{flags}:@var{level}:@var{description}:@var{type}:@var{alt-type}:@var{argname}:@var{default}:@var{argdef}:@var{value}}
 
 @table @var
 @item name
 This field contains a name tag for the group or option.  The name tag
 is used to specify the group or option in all communication with
 @command{gpgconf}.  The name tag is to be used @emph{verbatim}.  It is
 thus not in any escaped format.
 
 @item flags
 The flags field contains an @emph{unsigned number}.  Its value is the
 OR-wise combination of the following flag values:
 
 @table @code
 @item group (1)
 If this flag is set, this is a line describing a group and not an
 option.
 @end table
 
 The following flag values are only defined for options (that is, if
 the @code{group} flag is not used).
 
 @table @code
 @item optional arg (2)
 If this flag is set, the argument is optional.  This is never set for
 @var{type} @code{0} (none) options.
 
 @item list (4)
 If this flag is set, the option can be given multiple times.
 
 @item runtime (8)
 If this flag is set, the option can be changed at runtime.
 
 @item default (16)
 If this flag is set, a default value is available.
 
 @item default desc (32)
 If this flag is set, a (runtime) default is available.  This and the
 @code{default} flag are mutually exclusive.
 
 @item no arg desc (64)
 If this flag is set, and the @code{optional arg} flag is set, then the
 option has a special meaning if no argument is given.
 
 @item no change (128)
 If this flag is set, @command{gpgconf} ignores requests to change the
 value.  GUI frontends should grey out this option.  Note, that manual
 changes of the configuration files are still possible.
 @end table
 
 @item level
 This field is defined for options and for groups.  It contains an
 @emph{unsigned number} that specifies the expert level under which
 this group or option should be displayed.  The following expert levels
 are defined for options (they have analogous meaning for groups):
 
 @table @code
 @item basic (0)
 This option should always be offered to the user.
 
 @item advanced (1)
 This option may be offered to advanced users.
 
 @item expert (2)
 This option should only be offered to expert users.
 
 @item invisible (3)
 This option should normally never be displayed, not even to expert
 users.
 
 @item internal (4)
 This option is for internal use only.  Ignore it.
 @end table
 
 The level of a group will always be the lowest level of all options it
 contains.
 
 @item description
 This field is defined for options and groups.  The @emph{string} in
 this field contains a human-readable description of the option or
 group.  It can be displayed to the user of the GUI for informational
 purposes.  It is @emph{percent-escaped} and @emph{localized}.
 
 @item type
 This field is only defined for options.  It contains an @emph{unsigned
 number} that specifies the type of the option's argument, if any.  The
 following types are defined:
 
 Basic types:
 
 @table @code
 @item none (0)
 No argument allowed.
 
 @item string (1)
 An @emph{unformatted string}.
 
 @item int32 (2)
 A @emph{signed number}.
 
 @item uint32 (3)
 An @emph{unsigned number}.
 @end table
 
 Complex types:
 
 @table @code
 @item pathname (32)
 A @emph{string} that describes the pathname of a file.  The file does
 not necessarily need to exist.
 
 @item ldap server (33)
 A @emph{string} that describes an LDAP server in the format:
 
 @code{@var{hostname}:@var{port}:@var{username}:@var{password}:@var{base_dn}}
 
 @item key fingerprint (34)
 A @emph{string} with a 40 digit fingerprint specifying a certificate.
 
 @item pub key (35)
 A @emph{string} that describes a certificate by user ID, key ID or
 fingerprint.
 
 @item sec key (36)
 A @emph{string} that describes a certificate with a key by user ID,
 key ID or fingerprint.
 
 @item alias list (37)
 A @emph{string} that describes an alias list, like the one used with
 gpg's group option.  The list consists of a key, an equal sign and space
 separated values.
 @end table
 
 More types will be added in the future.  Please see the @var{alt-type}
 field for information on how to cope with unknown types.
 
 @item alt-type
 This field is identical to @var{type}, except that only the types
 @code{0} to @code{31} are allowed.  The GUI is expected to present the
 user the option in the format specified by @var{type}.  But if the
 argument type @var{type} is not supported by the GUI, it can still
 display the option in the more generic basic type @var{alt-type}.  The
 GUI must support all the defined basic types to be able to display all
 options.  More basic types may be added in future versions.  If the
 GUI encounters a basic type it doesn't support, it should report an
 error and abort the operation.
 
 @item argname
 This field is only defined for options with an argument type
 @var{type} that is not @code{0}.  In this case it may contain a
 @emph{percent-escaped} and @emph{localized string} that gives a short
 name for the argument.  The field may also be empty, though, in which
 case a short name is not known.
 
 @item default
 This field is defined only for options for which the @code{default} or
 @code{default desc} flag is set.  If the @code{default} flag is set,
 its format is that of an @emph{option argument} (@pxref{Format
 conventions}, for details).  If the default value is empty, then no
 default is known.  Otherwise, the value specifies the default value
 for this option.  If the @code{default desc} flag is set, the field is
 either empty or contains a description of the effect if the option is
 not given.
 
 @item argdef
 This field is defined only for options for which the @code{optional
 arg} flag is set.  If the @code{no arg desc} flag is not set, its
 format is that of an @emph{option argument} (@pxref{Format
 conventions}, for details).  If the default value is empty, then no
 default is known.  Otherwise, the value specifies the default argument
 for this option.  If the @code{no arg desc} flag is set, the field is
 either empty or contains a description of the effect of this option if
 no argument is given.
 
 @item value
 This field is defined only for options.  Its format is that of an
 @emph{option argument}.  If it is empty, then the option is not
 explicitly set in the current configuration, and the default applies
 (if any).  Otherwise, it contains the current value of the option.
 Note that this field is also meaningful if the option itself does not
 take a real argument (in this case, it contains the number of times
 the option appears).
 @end table
 
 
 @node Changing options
 @subsection Changing options
 
 The command @w{@code{--change-options @var{component}}} will attempt
 to change the options of the component @var{component} to the
 specified values.  @var{component} must be the string in the field
 @var{name} in the output of the @code{--list-components} command.  You
 have to provide the options that shall be changed in the following
 format on standard input:
 
 @code{@var{name}:@var{flags}:@var{new-value}}
 
 @table @var
 @item name
 This is the name of the option to change.  @var{name} must be the
 string in the field @var{name} in the output of the
 @code{--list-options} command.
 
 @item flags
 The flags field contains an @emph{unsigned number}.  Its value is the
 OR-wise combination of the following flag values:
 
 @table @code
 @item default (16)
 If this flag is set, the option is deleted and the default value is
 used instead (if applicable).
 @end table
 
 @item new-value
 The new value for the option.  This field is only defined if the
 @code{default} flag is not set.  The format is that of an @emph{option
 argument}.  If it is empty (or the field is omitted), the default
 argument is used (only allowed if the argument is optional for this
 option).  Otherwise, the option will be set to the specified value.
 @end table
 
 @noindent
 The output of the command is the same as that of
 @code{--check-options} for the modified configuration file.
 
 Examples:
 
 To set the force option, which is of basic type @code{none (0)}:
 
 @example
 $ echo 'force:0:1' | gpgconf --change-options dirmngr
 @end example
 
 To delete the force option:
 
 @example
 $ echo 'force:16:' | gpgconf --change-options dirmngr
 @end example
 
 The @code{--runtime} option can influence when the changes take
 effect.
 
 
 @node Listing global options
 @subsection Listing global options
 
 Sometimes it is useful for applications to look at the global options
 file @file{gpgconf.conf}.
 The colon separated listing format is record oriented and uses the first
 field to identify the record type:
 
 @table @code
 @item k
 This describes a key record to start the definition of a new ruleset for
 a user/group.  The format of a key record is:
 
   @code{k:@var{user}:@var{group}:}
 
 @table @var
 @item user
 This is the user field of the key.  It is percent escaped.  See the
 definition of the gpgconf.conf format for details.
 
 @item group
 This is the group field of the key.  It is percent escaped.
 @end table
 
 @item r
 This describes a rule record. All rule records up to the next key record
 make up a rule set for that key.  The format of a rule record is:
 
   @code{r:::@var{component}:@var{option}:@var{flag}:@var{value}:}
 
 @table @var
 @item component
 This is the component part of a rule.  It is a plain string.
 
 @item option
 This is the option part of a rule.  It is a plain string.
 
 @item flag
 This is the flags part of a rule.  There may be only one flag per rule
 but by using the same component and option, several flags may be
 assigned to an option.  It is a plain string.
 
 @item value
 This is the optional value for the option.  It is a percent escaped
 string with a single quotation mark to indicate a string.  The quotation
 mark is only required to distinguish between no value specified and an
 empty string.
 @end table
 
 @end table
 
 @noindent
 Unknown record types should be ignored.  Note that there is intentionally
 no feature to change the global option file through @command{gpgconf}.
 
 
 @node Querying versions
 @subsection Get and compare software versions.
 
 The GnuPG Project operates a server to query the current versions of
 software packages related to GnuPG.  @command{gpgconf} can be used to
 access this online database.  To allow for offline operations, this
 feature works by having @command{dirmngr} download a file from
 @code{https://versions.gnupg.org}, checking the signature of that file
 and storing the file in the GnuPG home directory.  If
 @command{gpgconf} is used and @command{dirmngr} is running, it may ask
 @command{dirmngr} to refresh that file before itself uses the file.
 
 The command @option{--query-swdb} returns information for the given
 package in a colon delimited format:
 
 @table @var
 
 @item name
 This is the name of the package as requested.  Note that "gnupg" is a
 special name which is replaced by the actual package implementing this
 version of GnuPG.  For this name it is also not required to specify a
 version because @command{gpgconf} takes its own version in this case.
 
 @item iversion
 The currently installed version or an empty string.  The value is
 taken from the command line argument but may be provided by gpg
 if not given.
 
 @item status
 The status of the software package according to this table:
 @table @code
 @item -
 No information available.  This is either because no current version
 has been specified or due to an error.
 @item ?
 The given name is not known in the online database.
 @item u
 An update of the software is available.
 @item c
 The installed version of the software is current.
 @item n
 The installed version is already newer than the released version.
 @end table
 
 @item urgency
 If the value (the empty string should be considered as zero) is
 greater than zero an important update is available.
 
 @item error
 This returns an @command{gpg-error} error code to distinguish between
 various failure modes.
 
 @item filedate
 This gives the date of the file with the version numbers in standard
 ISO format (@code{yyyymmddThhmmss}).  The date has been extracted by
 @command{dirmngr} from the signature of the file.
 
 @item verified
 This gives the date in ISO format the file was downloaded.  This value
 can be used to evaluate the freshness of the information.
 
 @item version
 This returns the version string for the requested software from the
 file.
 
 @item reldate
 This returns the release date in ISO format.
 
 @item size
 This returns the size of the package as decimal number of bytes.
 
 @item hash
 This returns a hexified SHA-2 hash of the package.
 
 @end table
 
 @noindent
 More fields may be added in future to the output.

 @mansect description
 The @command{gpg-preset-passphrase} is a utility to seed the internal
 cache of a running @command{gpg-agent} with passphrases.  It is mainly
 useful for unattended machines, where the usual @command{pinentry} tool
 may not be used and the passphrases for the to be used keys are given at
 machine startup.
 
 This program works with GnuPG 2 and later.  GnuPG 1.x is not supported.
 
 Passphrases set with this utility don't expire unless the
 @option{--forget} option is used to explicitly clear them from the
 cache --- or @command{gpg-agent} is either restarted or reloaded (by
 sending a SIGHUP to it).  Note that the maximum cache time as set with
 @option{--max-cache-ttl} is still honored.  It is necessary to allow
 this passphrase presetting by starting @command{gpg-agent} with the
 @option{--allow-preset-passphrase}.

 @noindent
 @command{gpg-preset-passphrase} is invoked this way:
 
 @example
 gpg-preset-passphrase [options] [command] @var{cacheid}
 @end example
 
 @var{cacheid} is either a 40 character keygrip of hexadecimal
 characters identifying the key for which the passphrase should be set
 or cleared.  The keygrip is listed along with the key when running the
 command: @code{gpgsm --with-keygrip --list-secret-keys}.
 Alternatively an arbitrary string may be used to identify a
 passphrase; it is suggested that such a string is prefixed with the
 name of the application (e.g @code{foo:12346}).  Scripts should always
 use the option @option{--with-colons}, which provides the keygrip in a
 "grp" line (cf. @file{doc/DETAILS})/
 
 @noindent
 One of the following command options must be given:
 
 @table @gnupgtabopt
 @item --preset
 @opindex preset
 Preset a passphrase. This is what you usually will
 use. @command{gpg-preset-passphrase} will then read the passphrase from
 @code{stdin}.
 
 @item --forget
 @opindex forget
 Flush the passphrase for the given cache ID from the cache.
 
 @end table
 
 @noindent
 The following additional options may be used:
 
 @table @gnupgtabopt
 @item -v
 @itemx --verbose
 @opindex verbose
 Output additional information while running.
 
 @item -P @var{string}
 @itemx --passphrase @var{string}
 @opindex passphrase
 Instead of reading the passphrase from @code{stdin}, use the supplied
 @var{string} as passphrase.  Note that this makes the passphrase visible
 for other users.

 @include opt-homedir.texi
 
 @item --agent-program @var{file}
 @opindex agent-program
 Specify the agent program to be started if none is running.  The
 default value is determined by running @command{gpgconf} with the
 option @option{--list-dirs}.  Note that the pipe symbol (@code{|}) is
 used for a regression test suite hack and may thus not be used in the
 file name.
 
 @item --dirmngr-program @var{file}
 @opindex dirmngr-program
 Specify the directory manager (keyserver client) program to be started
 if none is running.  This has only an effect if used together with the
 option @option{--dirmngr}.
 
 @item --dirmngr
 @opindex dirmngr
 Connect to a running directory manager (keyserver client) instead of
 to the gpg-agent.  If a dirmngr is not running, start it.
 
 @item -S
 @itemx --raw-socket @var{name}
 @opindex raw-socket
 Connect to socket @var{name} assuming this is an Assuan style server.
 Do not run any special initializations or environment checks.  This may
 be used to directly connect to any Assuan style socket server.
 
 @item -E
 @itemx --exec
 @opindex exec
 Take the rest of the command line as a program and it's arguments and
 execute it as an Assuan server. Here is how you would run @command{gpgsm}:
 @smallexample
  gpg-connect-agent --exec gpgsm --server
 @end smallexample
 Note that you may not use options on the command line in this case.
 
 @item --no-ext-connect
 @opindex no-ext-connect
 When using @option{-S} or @option{--exec}, @command{gpg-connect-agent}
 connects to the Assuan server in extended mode to allow descriptor
 passing.  This option makes it use the old mode.
 
 @item --no-autostart
 @opindex no-autostart
 Do not start the gpg-agent or the dirmngr if it has not yet been
 started.
 
 @item -r @var{file}
 @itemx --run @var{file}
 @opindex run
 Run the commands from @var{file} at startup and then continue with the
 regular input method.  Note, that commands given on the command line are
 executed after this file.
 
 @item -s
 @itemx --subst
 @opindex subst
 Run the command @code{/subst} at startup.
 
 @item --hex
 @opindex hex
 Print data lines in a hex format and the ASCII representation of
 non-control characters.
 
 @item --decode
 @opindex decode
 Decode data lines.  That is to remove percent escapes but make sure that
 a new line always starts with a D and a space.

 @node Controlling gpg-connect-agent
 @subsection Control commands
 
 While reading Assuan commands, gpg-agent also allows a few special
 commands to control its operation.  These control commands all start
 with a slash (@code{/}).
 
 @table @code
 
 @item /echo @var{args}
 Just print @var{args}.
 
 @item /let @var{name} @var{value}
 Set the variable @var{name} to @var{value}.  Variables are only
 substituted on the input if the @command{/subst} has been used.
 Variables are referenced by prefixing the name with a dollar sign and
 optionally include the name in curly braces.  The rules for a valid name
 are identically to those of the standard bourne shell.  This is not yet
 enforced but may be in the future.  When used with curly braces no
 leading or trailing white space is allowed.
 
 If a variable is not found, it is searched in the environment and if
 found copied to the table of variables.
 
 Variable functions are available: The name of the function must be
 followed by at least one space and the at least one argument.  The
 following functions are available:
 
 @table @code
 @item get
 Return a value described by the argument.  Available arguments are:
 
 @table @code
 @item cwd
 The current working directory.
 @item homedir
 The gnupg homedir.
 @item sysconfdir
 GnuPG's system configuration directory.
 @item bindir
 GnuPG's binary directory.
 @item libdir
 GnuPG's library directory.
 @item libexecdir
 GnuPG's library directory for executable files.
 @item datadir
 GnuPG's data directory.
 @item serverpid
 The PID of the current server. Command @command{/serverpid} must
 have been given to return a useful value.
 @end table
 
 @item unescape @var{args}
 Remove C-style escapes from @var{args}.  Note that @code{\0} and
 @code{\x00} terminate the returned string implicitly.  The string to be
 converted are the entire arguments right behind the delimiting space of
 the function name.
 
 @item unpercent @var{args}
 @itemx unpercent+ @var{args}
 Remove percent style escaping from @var{args}.  Note that @code{%00}
 terminates the string implicitly.  The string to be converted are the
 entire arguments right behind the delimiting space of the function
 name. @code{unpercent+} also maps plus signs to a spaces.
 
 @item percent @var{args}
 @itemx percent+ @var{args}
 Escape the @var{args} using percent style escaping.  Tabs, formfeeds,
 linefeeds, carriage returns and colons are escaped. @code{percent+} also
 maps spaces to plus signs.
 
 @item errcode @var{arg}
 @itemx errsource @var{arg}
 @itemx errstring @var{arg}
 Assume @var{arg} is an integer and evaluate it using @code{strtol}.  Return
 the gpg-error error code, error source or a formatted string with the
 error code and error source.
 
 
 @item +
 @itemx -
 @itemx *
 @itemx /
 @itemx %
 Evaluate all arguments as long integers using @code{strtol} and apply
 this operator.  A division by zero yields an empty string.
 
 @item !
 @itemx |
 @itemx &
 Evaluate all arguments as long integers using @code{strtol} and apply
 the logical operators NOT, OR or AND.  The NOT operator works on the
 last argument only.
 
 
 @end table
 
 
 @item /definq @var{name} @var{var}
 Use content of the variable @var{var} for inquiries with @var{name}.
 @var{name} may be an asterisk (@code{*}) to match any inquiry.
 
 
 @item /definqfile @var{name} @var{file}
 Use content of @var{file} for inquiries with @var{name}.
 @var{name} may be an asterisk (@code{*}) to match any inquiry.
 
 @item /definqprog @var{name} @var{prog}
 Run @var{prog} for inquiries matching @var{name} and pass the
 entire line to it as command line arguments.
 
 @item /datafile @var{name}
 Write all data lines from the server to the file @var{name}.  The file
 is opened for writing and created if it does not exists.  An existing
 file is first truncated to 0.  The data written to the file fully
 decoded.  Using a single dash for @var{name} writes to stdout.  The
 file is kept open until a new file is set using this command or this
 command is used without an argument.
 
 @item /showdef
 Print all definitions
 
 @item /cleardef
 Delete all definitions
 
 @item /sendfd @var{file} @var{mode}
 Open @var{file} in @var{mode} (which needs to be a valid @code{fopen}
 mode string) and send the file descriptor to the server.  This is
 usually followed by a command like @code{INPUT FD} to set the
 input source for other commands.
 
 @item /recvfd
 Not yet implemented.
 
 @item /open @var{var} @var{file} [@var{mode}]
 Open @var{file} and assign the file descriptor to @var{var}.  Warning:
 This command is experimental and might change in future versions.
 
 @item /close @var{fd}
 Close the file descriptor @var{fd}.  Warning: This command is
 experimental and might change in future versions.
 
 @item /showopen
 Show a list of open files.
 
 @item /serverpid
 Send the Assuan command @command{GETINFO pid} to the server and store
 the returned PID for internal purposes.
 
 @item /sleep
 Sleep for a second.
 
 @item /hex
 @itemx /nohex
 Same as the command line option @option{--hex}.
 
 @item /decode
 @itemx /nodecode
 Same as the command line option @option{--decode}.
 
 @item /subst
 @itemx /nosubst
 Enable and disable variable substitution.  It defaults to disabled
 unless the command line option @option{--subst} has been used.
 If /subst as been enabled once, leading whitespace is removed from
 input lines which makes scripts easier to read.
 
 @item /while @var{condition}
 @itemx /end
 These commands provide a way for executing loops.  All lines between
 the @code{while} and the corresponding @code{end} are executed as long
 as the evaluation of @var{condition} yields a non-zero value or is the
 string @code{true} or @code{yes}.  The evaluation is done by passing
 @var{condition} to the @code{strtol} function.  Example:
 
 @smallexample
   /subst
   /let i 3
   /while $i
-    /echo loop couter is $i
+    /echo loop counter is $i
     /let i $@{- $i 1@}
   /end
 @end smallexample
 
 @item /if @var{condition}
 @itemx /end
 These commands provide a way for conditional execution.  All lines between
 the @code{if} and the corresponding @code{end} are executed only if
 the evaluation of @var{condition} yields a non-zero value or is the
 string @code{true} or @code{yes}.  The evaluation is done by passing
 @var{condition} to the @code{strtol} function.
 
 @item /run @var{file}
 Run commands from @var{file}.
 
 @item /bye
 Terminate the connection and the program.
 
 @item /help
 Print a list of available control commands.

 If no dirmngr is running, a new instances will be started but this is
 in general not a good idea due to the huge performance overhead.
 
 @noindent
 The usual way to run this tool is either:
 
 @example
 dirmngr-client @var{acert}
 @end example
 
 @noindent
 or
 
 @example
 dirmngr-client <@var{acert}
 @end example
 
 Where @var{acert} is one DER encoded (binary) X.509 certificates to be
 tested.

 The return value of this command is
 @end ifclear
 
 @mansect return value
 @ifset isman
 @command{dirmngr-client} returns these values:
 @end ifset
 @table @code
 
 @item 0
 The certificate under question is valid; i.e. there is a valid CRL
 available and it is not listed there or the OCSP request returned that
 that certificate is valid.
 
 @item 1
 The certificate has been revoked
 
 @item 2 (and other values)
 There was a problem checking the revocation state of the certificate.
 A message to stderr has given more detailed information.  Most likely
 this is due to a missing or expired CRL or due to a network problem.

 @mansect options
 @noindent
 @command{dirmngr-client} may be called with the following options:
 
 
 @table @gnupgtabopt
 @item --version
 @opindex version
 Print the program version and licensing information.  Note that you cannot
 abbreviate this command.
 
 @item --help, -h
 @opindex help
 Print a usage message summarizing the most useful command-line options.
 Note that you cannot abbreviate this command.
 
 @item --quiet, -q
 @opindex quiet
 Make the output extra brief by suppressing any informational messages.
 
 @item -v
 @item --verbose
 @opindex v
 @opindex verbose
 Outputs additional information while running.
 You can increase the verbosity by giving several
 verbose commands to @sc{dirmngr}, such as @samp{-vv}.
 
 @item --pem
 @opindex pem
 Assume that the given certificate is in PEM (armored) format.
 
 @item --ocsp
 @opindex ocsp
 Do the check using the OCSP protocol and ignore any CRLs.
 
 @item --force-default-responder
 @opindex force-default-responder
 When checking using the OCSP protocol, force the use of the default OCSP
 responder.  That is not to use the Reponder as given by the certificate.
 
 @item --ping
 @opindex ping
 Check whether the dirmngr daemon is up and running.
 
 @item --cache-cert
 @opindex cache-cert
 Put the given certificate into the cache of a running dirmngr.  This is
 mainly useful for debugging.
 
 @item --validate
 @opindex validate
 Validate the given certificate using dirmngr's internal validation code.
 This is mainly useful for debugging.
 
 @item --load-crl
 @opindex load-crl
 This command expects a list of filenames with DER encoded CRL files.
 With the option @option{--url} URLs are expected in place of filenames
 and they are loaded directly from the given location.  All CRLs will be
 validated and then loaded into dirmngr's cache.
 
 @item --lookup
 @opindex lookup
 Take the remaining arguments and run a lookup command on each of them.
 The results are Base-64 encoded outputs (without header lines).  This
 may be used to retrieve certificates from a server. However the output
 format is not very well suited if more than one certificate is returned.
 
 @item --url
 @itemx -u
 @opindex url
 Modify the @command{lookup} and @command{load-crl} commands to take an URL.
 
 @item --local
 @itemx -l
 @opindex url
 Let the @command{lookup} command only search the local cache.
 
 @item --squid-mode
 @opindex squid-mode
 Run @sc{dirmngr-client} in a mode suitable as a helper program for
 Squid's @option{external_acl_type} option.

 @mansect description
 Sometimes simple encryption tools are already in use for a long time
 and there might be a desire to integrate them into the GnuPG
 framework.  The protocols and encryption methods might be non-standard
 or not even properly documented, so that a full-fledged encryption
 tool with an interface like @command{gpg} is not doable.
 @command{symcryptrun} provides a solution: It operates by calling the
 external encryption/decryption module and provides a passphrase for a
 key using the standard @command{pinentry} based mechanism through
 @command{gpg-agent}.
 
 Note, that @command{symcryptrun} is only available if GnuPG has been
 configured with @samp{--enable-symcryptrun} at build time.

 @command{symcryptrun} is invoked this way:
 
 @example
 symcryptrun --class CLASS --program PROGRAM --keyfile KEYFILE
    [--decrypt | --encrypt] [inputfile]
 @end example
 @mancont
 
 For encryption, the plain text must be provided on STDIN or as the
 argument @var{inputfile}, and the ciphertext will be output to STDOUT.
 For decryption vice versa.
 
 @var{CLASS} describes the calling conventions of the external tool.
 Currently it must be given as @samp{confucius}.  @var{PROGRAM} is
 the full filename of that external tool.
 
 For the class @samp{confucius} the option @option{--keyfile} is
 required; @var{keyfile} is the name of a file containing the secret key,
 which may be protected by a passphrase.  For detailed calling
 conventions, see the source code.
 
 @noindent
 Note, that @command{gpg-agent} must be running before starting
 @command{symcryptrun}.
 
 @noindent
 The following additional options may be used:
 
 @table @gnupgtabopt
 @item -v
 @itemx --verbose
 @opindex verbose
 Output additional information while running.
 
 @item -q
 @item --quiet
 @opindex q
 @opindex quiet
 Try to be as quiet as possible.
 
 @include opt-homedir.texi
 
 
 @item --log-file @var{file}
 @opindex log-file
 Append all logging output to @var{file}.  Use @file{socket://} to log
 to socket.  Default is to write logging information to STDERR.
 
 @end table
 
 @noindent
 The possible exit status codes of @command{symcryptrun} are:
 
 @table @code
 @item 0
         Success.
 @item 1
         Some error occurred.
 @item 2
         No valid passphrase was provided.
 @item 3
         The operation was canceled by the user.
