GAR

"GAR is also the name of our [LNX-BBC] software build toolset. Common backronyms we've seen include "GAR Are Recursive" and "Gmake Autobuild Runtime". It is a system similar in function (and nearly identical in purpose) to the BSD ports system. It is a set of Makefiles that we use to compile all of the software in the BBC and turn them into an ISO9660 CD-ROM image file."
