[Rivet] AIDA branch closed (gzip next...)

[James Monk]

That would actually be a nice alternative - modify the rivet python script to pipe the input through gunzip if it detects a gzipped file.  Then we don’t need the zlib dependency.  I presume performance would be more-or-less identical - does anyone know for sure?
