3Initial Package Version: 2.5.31
4Origin: Debian
5Description: This fixes a ton of things. I'm not entirely sure what, but
6 it's all stuff that Debian thought to be broken, and I trust them.
7 All the non-code changes have been stripped (otherwise it would
8 be gargantuan). I've been using this patch for a few months now
9 and it makes flex not suck anymore. That's a good thing.
