`anthologize' converts S-format to I-format.  It takes a collection of #P
blocks with offsets and translates it to offsetless P blocks and an #I list.
Can recognize and coalesce identical blocks, or blocks that are the same 
modulo X- or Y-axis reflection.  It is written in Perl.  It uses standard 
input.  `anthologize' is intended to work with J.Conway's Life patterns.

The result of `lifeconv' differs from result of `anthologize'.  `lifeconv' 
selects #P blocks by its own algorithm.
