I think this description is not wrong per-se but misses the much more important point. In the very early days of Git, the objects were named after SHA-1 of deflated loose object representation, which meant that tweak in zlib or change of compression level would give the same object different names X-<. This program was to convert an ancient history with these objects and rewrite them to match the new object naming scheme where the name comes from a hash of the inflated representation. > By now the need for conversion of the very early repositories is less > relevant, we no longer need to keep it in contrib; remove it. I am not sure if removal of it matters, and I suspect that we saw no reaction from anybody because nobody thought it deserves the brain-cycle to decide whether to remove it. I dunno.
