BitBake is, at its simplest, a tool for executing tasks and managing metadata. As such, its similarities to GNU make and other build tools are readily apparent. It was inspired by Portage, the package management system used by the Gentoo Linux distribution.
BitBake is the basis of the OpenEmbedded project, which is being used to build and maintain a number of embedded Linux distributions.

OE-Core needs a fairly up-to-date version of BitBake; at minimum the most recent stable version is recommended. A sanity check on the BitBake version is performed at startup; if it is too old you will need to update before continuing.
