# This CGI script does the following.
#   1. Compile all arbitrary fields submitted (no validation is done.)
#   2. If GnuPG encryption is enabled, encrypt the content.
#   3. Send the message to the specified recipient.
#
# Note: This is obviously not a super-robust solution. It is what it
#       is: a super-simple way to start getting form data without a
#       lot of backend programming.
