Proposing to replace something with code that is not (yet) available is not really helpful. The code you have linked to above seems to be a rather limited parser that can extract some parts from packages files (namely, names and versions). It is in no way a replacement for apt-show-versions, at least not for now. We could probably easily rewrite apt-show-versions in C++ using libapt-pkg and get an immensive speed up this way, as we'd be able to utilise APT's cache (the cache should have all required information in it anyway). -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/. -- To UNSUBSCRIBE, email to debian-derivatives-requ...@lists.debian.org with a subject of "unsubscribe".
