I have a new flat file CMS called razorCMS, give it a try, it is offered under the GPLv3 licence.
razorCMS » Home
It is currently in it's first RC release and is a new system comprising of small parts of nanoCMS (most is new though especially the structure), the website explains all.
I am currently looking for some testers and users, the system is at RC but is very usable, I am looking to spend some time squashing bugs before releasing a stable version.
The system comes in one flavour, core, which is a stripped down to the max version with just enough to make it usable, no editors or anything like that. Then you add on the blade packs which add the extra functionality as you want it, hopefully this will give everyone the kind of system they want without the functionality they do not use. This should keeps things simple and fast.
My aim is to keep the core install very basic, and have everything else as add on's.
I have a dedicated forum for support and feedback, if your after a CMS without the need of a database, this might be for you.
