Also for the archives - if you are scripting in Perl, see 
IO::Compress::Deflate.  Python has zlib.compress(), which I *think* 
implements a bare deflate.  And Ruby has Zlib::Deflate/Zlib::ZStream.  
 From what I can tell, all of these are "built-in" to the standard 
distributions in recent versions.

One could also invoke one of these interpreters from a bash script as 
well :)
