=head1 NAME
cleandir - remove unused files from directory
=head1 SYNOPSIS
cleandir [-d days] [-n] [-v] [-s] directory...
=head1 DESCRIPTION
cleandir recursively searches each directory given on the commandline
for files and subdirectories which have not been accessed for n days and
deletes them.
=head1 OPTIONS
=over 4
=item B<-d days>
Delete files which have not been accessed for the given number of days.
The default is 14.
=item B<-n>
No-op. Don't delete any files.
=item B<-v>
Verbose. Can be repeated to increase verbosity.
=item B<-s>
Skip sockets and named pipes. Some programs (notably X11 and some
databases) create sockets and named pipes in /tmp and foolishly expect
them to survive. This option exists to humour them.

=head1 AUTHOR
Peter J. Holzer <hjp@hjp.at>. Thanks to Chris Mason for some
enhancements.
