#!/usr/bin/perl
# Drop-in replacement for /usr/bin/mail that uses Mail.app (via an
# applescript) rather than sendmail to send mail.  Unlike /usr/bin/mail,
# you can't use it for reading mail.
#
# usage: mail [<options>] <recipients>
#   options:
#     -v       be verbose
#     -g       activate Mail.app to approve the message
#     -F <from>  specify the From: address
#     -R <replyto> specify the Reply-To: address
#     -b <bcc>   specify Bcc: recipients in a comma-separated list
#     -c <cc>    specify Cc: recipients in a comma-separated list
#     -s <subject> specify the message subject
#
# The body of the message is read from standard input.
