Restore of the game "Operation Cleaner 2" originally by Jan Nyman.
I downloaded it from archive.org and ported to Linux, mostly intact.
It retains the original license, see LICENSE for details.
I've used the "sdl12-compat" package on fedora (SDL 1.2 runtime compatibility library using SDL 2.0).
Run make in the current folder. This will build the target binaries.
Run oc2 in the oc2 folder to play the game.
