In addition, the file:open(Name, Options) allows you to passed the atom `compressed'
in the Options list to have files be compressed/uncompressed when written/read.
(Seems to be still undocumented in R9.)

If you are interested in compressing Erlang terms, it can be done like this:

term_to_binary(Term, [compressed]).


binary_to_term/1 will automatically uncompress such a binary.
