Rebuild
Rebuild is a recreation of the famous build/bud, based on the DMD frontend. It was written because of general unhappiness with build/bud.
Rebuild is a component of DSSS, and so is available for download as part of DSSS at http://svn.dsource.org/projects/dsss/downloads/
There is a very sparse README for rebuild: http://www.dsource.org/projects/dsss/browser/trunk/rebuild/README .
Before using rebuild alone, please consider the advantages of using DSSS with rebuild, rather than rebuild in isolation.
Configuration
rebuild uses configuration files for its targets. Nearly everything is configurable, so you can retarget it and even cross-compile.
The configuration directory is named rebuild.conf . You can either leave it next to the binary, or (if you install in a Unix style), rename it /etc/rebuild or ~/.rebuild .
