Disasterclass is a tool to process a Minecraft world. The plan is to let you use it to age your mansion by a thousand years, throw your castle underwater, or run your own filters.
Disasterclass is written in the D programming language, and you'll need DMD v2.063 or later (in your path as dmd). You'll also need Python to compile the item data.
After checking out the source, move to the src/ folder and type make cma_release to build a release version in Build/Release_Staging/<version>. This builds an x64 version by default. If you want a 32-bit version, change the line
ARCHFLAG := -m64
to
ARCHFLAG := -m32
and rebuild.
Building has only been extensively tested on OS X, but Disasterclass should also compile on Windows (if you can get a working build script) and Linux.
Disasterclass changes a world in-place. Back up your world before running.
Disasterclass currently runs from the command line. (I apologise in advance.) Type ./Disasterclass to get a list of what you can do. Commands follow this form:
./Disasterclass <command-name> --world <path-to-Minecraft-world>
The main function to age a world is stoneage.
Developer docs are automatically built from source on release builds in Build/API_Documentation. You can find in-depth documentation on how Disasterclass's multicore dispatch works at Documentation/Multicore.md.

Disasterclass is far from finished, and there's plenty that needs refinement. The chunk loading/saving and multicore architecture are pretty much there; the light recalculation isn't on par with Minecraft (also it is crazy slow). The current world filters are quite basic at the moment, and could benefit from refinement — this is an aesthetic call, however.
