2155	"patch for ""compressdoc"" to automatically use best compression method"	Lars Bamberger	dnicholson@…	"In chapter 3 of the book (Compressing Man and Info Pages) there is a script called ""compressdoc"".
I have added an option '--automatic'. The idea is: Compress using either gzip or bzip2, depending on the size of the file to be compressed. Files larger than 5 kB are bziped, files larger than 1 kB are gziped and files smaller than 1 kB are not compressed.

Here follows the diff from version 20060311.0028 of the script to my version:

< #     - offer an option to automagically choose the best compression
< #       methed on a per page basis (eg. check which of
< #       gzip/bzip2/whatever is the most effective, page per page);
