 intro = """
 This script creates a temporary directory to use as a homedir for
 testing key generation tasks with the correct permissions, along
 with a gpg.conf file containing the same configuration options
 listed in the HOWTO.
 
 You may wish to change the order of the cipher preferences or
 remove those not relevant to your installation.  These
 configuration parameters assume that all ciphers and digests are
 installed and available rather than limiting to the default
 ciphers and digests.
 
 The script prompts for a directory name to be installed as a hidden
 directory in the user's home directory on POSIX systems.  So if you
 enter "gnupg-temp" on a Linux, BSD or OS X system, it will create
 "~/.gnupg-temp" (you do not need to enter the leading dot).
 
 This script has not been tested on Windows systems and may have
 unpredictable results.  That said, it will not delete or copy over
 existing data.
 
 If the directory already exists, the script will terminate with a
 message telling you to specify a new directory name.  There is no
-default directory name.  
+default directory name.
