Seems a good idea! I might join and contribute the Ada compression / decompression part, which is already available: - complete inflate (decompression) code, in Zip-Ada since 1999 and in the Generic Image Decoder since 2010 - deflate code (compression) with one approach currently, in Zip-Ada since a few days We need to find a good name. Zada ?... (hmmm perhaps not a good one...) Cheers Gautier
