TODO
====

 * Add a utility to transform zlibrc files into config.c files and
compile them into the zlibc
 * Add support to compress files on the fly when writing them. (This would
only work if they are opened with the O_APPEND flag set)
 * Add support to uncompress files in place before changing them. This
mechanism would only kick in if the O_APPEND flag isn't set. These
files would stay uncompressed after use.
 * Make a daemon who maintains a global cache of uncompressed files, a little
bit like tcx. (Maybe also a special nfsd, but this would be slower :-( )
