Description:

mcs is a library and set of userland tools which abstract the storage
of configuration settings away from userland applications. It is hoped
that by using mcs, that the applications which use it will generally have
a more congruent feeling in regards to settings.
There have been other projects like this before (such as GConf), but
unlike those projects, mcs strictly handles abstraction. It does not
impose any specific data storage requirement, nor is it tied to any
desktop environment or software suite.
Because mcs is licenced under the BSD licence, it is hoped that many
applications will adopt it's use.
