 * The artifacts step is where source patches are committed, or written as "artifacts"
 * Steps:
 *  - A temporary directory is created in the downloaded source
 *  - On start, any files in that directory are restored into the source tree
 *  - After the patch functions have run, the temporary directory is emptied
 *  - Original versions of sources to be patched are written to the temporary directory
 *  - Finally, The patched files are written into source.
