== Adding a new package

* Create most of the files in the 'any' architecture for cross compiling
* Copy the directory structure from an existing package
    * APKG.yml goes into the $(ONL)/packages/base/any/foo/ directory
    * PKG.yml goes into the $(ONL)/packages/base/$ARCH/foo directory
        * Create for each $ARCH you intend to support
* Put code in $(ONL)/packages/base/any/foo/src
* Put package specific Makefiles in $(ONL)/packages/base/any/builds

* Run `make rebuild` in $(ONL)/packages/base/$ARCH/foo to rebuild the package cache
    * particularly if you see an error like:
      """ERROR:onlpm:'Package all does not exist.'"""
