- If you have a collection of small files binding them together and
- compressing the bunch at one might be an idea (disadvantage is
- slow access to last file etc).
-
- If you want a single small file to compress well use a static dictionary.
- For small .C file for example this one would contain "#include" file etc.
-
- Both ways do not need a slow compressor. A static dictionary will make
- compression slower because the dictionary will have to be parsed
- into the hash chains.
-
- If you can't use a static dictionary because the small files are
- unpredictable use higher order arithmetic compression. If that
- fails give up :-)
