I've just written a few packages which I think may be useful, and have made them available as free opensource on a personal website http://functionalley.eu.
I opted to host them there rather than  uploading them to Hackage, because they're part of a wider project.
The main offerings are; a regex-engine which is polymorphic in terms of the type of the input-data, a traditional character-based regex-engine derived from it, and an application to determine the most efficient order in which to pack files into a given storage-space.

I understand this isn't the ideal venue in which announce new packages, but having looked briefly at the "haskell@haskell.org" mail-group and the cerebral offerings there, I'm rather concerned that my meagre offerings may resemble germs in a Dettol factory. Is there a more appropriate forum ?

If anyone has the time, I'd also greatly appreciate any feedback on this s/w.

Alistair Ward
