Stuff that rocks

Software on this page should have ideas similar to the suckless philosophy. The software must be FOSS licensed.

Libraries

This section is for small, usable development libraries, which can be used for writing software that sucks less. These should preferably be under the MIT/X consortium or BSD licenses, WTFPL, or public domain, or alternatively LGPL, because it makes them legally compatible with other suckless projects.
