The SHR distribution is built using the  OpenEmbedded software framework. Although it may seem initially daunting for new users, it is actually a very simple and effective way of cross compiling a custom Linux distro.

The basic idea behind OpenEmbedded? comes from the fact that a Linux distribution is generally put together from lots of different software packages, where specific versions must be downloaded and compiled, and the the resulting binaries can be written the standard places in a Linux file system. OpenEmbedded? allows us to specify for each package, specific details such as where the source code can be obtained, and which version should be compiled. It is also able to apply patches and take care of cross compiling for specific architectures.
