=head1 NAME

read-mail - Archive incoming mail

=head1 SYNOPSIS

  read-mail
  read-mail [options]

=head1 DESCRIPTION

This program is part of mharc and is the main program for archiving
mail.  It is generally called via cron.

This program does very little itself, but it invokes other mharc
scripts to do all the work.

If the file C<.noarchive> exists in mharc root directory, then this
program will do nothing and exit (unless the C<-force> option is
specified).  This is to allow one to disable incoming mail processing
while performing administrative tasks.

=head1 OPTIONS

This program is generally called without any command-line options
since it will read C<E<lt>mharc-rootE<gt>/lib/config.sh> for any configurable
options.  Regardless, the following command-line options are
available:

=over

=item C<-help>

Print out usage information.

=item C<-home> I<pathname>

Root pathname of archiving software and data.  If not specified,
C<SW_ROOT> variable in C<config.sh> is used, else the parent directory
that contains this program is used.

=item C<-man>

Print out entire manpage.

=item C<-verbose>

Print out status messages.

=back

=head1 FILES

=over

=item C<I<mharc-root>/lib/config.sh>

Main configuration file for mharc.
