Hi,
I've just put on the GitHub a small proxy server log collector written in Gambit-C:
https://github.com/wolneykien/squidmill
It uses some shared libraries also written in Gambit-C. One of them is the sqlite3 interface originally published on the Dumping Grounds. The other two are the general UNIX signal and domain socket libraries.
Thought these might be interesting/useful for the readers of this mailing list.
The code is released under GNU GPL v3+.
Paul.
