Nickolas will login to Freenode and change its nickname to each of the ones associated with your NickServ account, to ensure they are not dropped.
In order to build, you will need the following packages on Linux:
cmakelibircclient-devlibpcre3-dev
Build with ./make.sh.
./nickolas yournickname "YourNickServPassword"
Optionally add -v or --verbose to show additional information.
Contribution is welcome, this project was essentially me teaching myself C, so the quality is what you'd expect.
