/* The GnuPG project consists of many components. Error codes are
* exchanged between all components. The common error codes and their
* user-presentable descriptions are kept into a shared library to
* allow adding new error codes and components without recompiling any
* of the other components. In addition to error codes this library
* also features several other groups of functions which are common to
* all GnuPG components. They may be used by independet project as
* well. The interfaces will not change in a backward incompatible way.
*
* An error code together with an error source build up an error
* value. As the error value is been passed from one component to
* another, it preserves the information about the source and nature
* of the error.
*
* A component of the GnuPG project can define the following macros to
* tune the behaviour of the library:
*
* GPG_ERR_SOURCE_DEFAULT: Define to an error source of type
* gpg_err_source_t to make that source the default for gpg_error().
* Otherwise GPG_ERR_SOURCE_UNKNOWN is used as default.
*
* GPG_ERR_ENABLE_GETTEXT_MACROS: Define to provide macros to map the
* internal gettext API to standard names. This has only an effect on
* Windows platforms.
*
* GPGRT_ENABLE_ES_MACROS: Define to provide "es_" macros for the
* estream functions.
*
* GPGRT_ENABLE_LOG_MACROS: Define to provide short versions of the
* log functions.
*
* GPGRT_ENABLE_ARGPARSE_MACROS: Needs to be defined to provide the
* mandatory macros of the argparse interface.
