+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.
