Okay.

This is only for OS X and Linux.  I have no idea how to compile this for Windows, Windows people: good luck, post a binary if you manage to do it.

^^ is a modified cgminer for vertcoin that'll run on the http://vtc.pool.pm pool!

Extract, then run

./configure --enable-opencl --enable-scrypt && make

then run cgminer as normal for a scrypt cryptocurrency.

CAVEAT: this is a very dirty hack originally done by Trullala.  It hardcodes the nfactor, so it will only work through 2014!  A future version which handles the vertcoin nfactor more elegantly may be forthcoming.
