tidy-cache is a plugin for YUM, a software management system found in many Linux distributions. It helps to minimize the size of YUM's cache directory by deleting RPM packages files if newer versions of the same package are also present in the cache. You can exclude specific packages from being tested and you can set the number of old versions to keep in the cache.
tidy-rpm-cache.py is a Python script that removes RPM package files from a cache (i.e. a collection of directories) if a newer version of that package exists. It may be useful if you wish to minimize the disk space used by locally stored update packages. You can specify any number of paths of directories to search, and you can also exclude specific packages from being tested for obsolescence.

DYE is the Do-it-Yourself Embedded Environment Framework, a cross-development uClib-based toolchain and base system framework which is composed of the required source tarballs and patches and scripts to build the whole thing. The main goal is having total control about all pieces assembled for an embedded environment, starting from the toolchain and using a very easy and customizable set of Bash scripts to do everything.
