=head1 NAME
email2page - converts RFC822 email text into text suitable for paging
=head1 SYNOPSIS
email2page [-C CONF] [-h]
=head1 OPTIONS
=over 4
=item -C CONF
Read the configuration file CONF instead of /etc/sendpage/email2page.conf for the
rewriting rules.
=item -h
Display a summary of all the available command line options (and there
sure aren't many).
=back
=head1 DESCRIPTION
This tool is used to break down an email into a shortened version, using
a configurable set of rewriting rules, found in /etc/sendpage/email2page.conf.
email2page reads STDIN, and writes to STDOUT. Any errors will be reported
on STDERR. It was designed to be used with 'sendpage'.
=head1 AUTHOR
Kees Cook <kees@outflux.net>
=head1 BUGS
All the bugs with the program will probably come from the config file, as
several of the items are run with Perl's 'eval' statement. Please see the
documentation in the /etc/sendpage/email2page.conf file.
