=head1 NAME
clipfilter - Run various conversions for your clipboard data.
=head1 USAGE
# (copy some stuff)
$ clipfilter -html
# (paste, with html entities substituted in)
# or URI-escaping:
$ clipfilter -uri
# or pipe through an arbitrary program, like `tac`, the backwards cat:
$ clipfilter tac
# Note: currently, this just dumps everything to open2() and reads
# everything back. It could possibly create a deadlock, but I haven't
# found the case that causes this, yet.
=head1 MOTIVATION
A very frequent user pattern is to copy something, edit it in some rote way,
and then paste it back. Writing your own filter scripts will make it even more
useful.
=head1 BUGS
Current weirdness when piping this to some programs, like 'wc' and 'tail'.
I will work on this.
