=head1 NAME
awm - Archive Weasel's Mail
=head1 SYNOPSIS
=over
=item B<awm> [B<--help>]
=item B<awm> [B<--quiet>] [B<--verbose> [B<--verbose>]] [B<--older=>I<date>] B<--base=>I<base> [I<folder> [I<folder> ...]]
=back
=head1 DESCRIPTION
B<awm> is a simple mail archiver for MailDir style mail folders. It moves mails
older than the specified time to I<folder>.I<yyyy.mm> folders where I<yyyy.mm>
is the date when the mail was received (last Received header) or sent (Date
header) if no Received header can be found.
It archives the Maildir folder I<base> as well as all subfolders (Maildirs in the
same directory as I<base> that name starts with a period (B<.>)). If you list
one of more folders it will only archive them.
=head1 OPTIONS
=over
=item B<--verbose>
Verbose mode. Causes B<awm> to print debugging messages about its progress. May
be used more than once to increase verbosity.
=item B<--quiet>
Quiet mode. Be even more quient than normally (supress some warnings).
=item B<--help>
Print a short help and exit sucessfully.
=item B<--version>
Print version number and exit sucessfully.
=item B<--base>=I<base>
Specify the base of B<awm>'s operation. Example: C<--base=$(HOME)/Maildir>.
=item B<--older>=I<date>
Archive mails older than the specified date. Example: C<--older='-2 months'>
or C<--older='2002-01-01'>. Defaults to two months ago. See
C<Time::ParseDate(3)> for reognised formats.
