 # This is a buildbot configuration file containing a tagged list of files
 # processed by the stage/archive scripts. The known tags are:
 #
 # filename: Name of the file in the build output directory.
 # arch:     List of CPU architectures for which this file should be processed
 #           (values are based on the strings returned by python's
 #           platform.architecture() function).
 # buildtype: List of build types for which this file should be processed.
 # archive: The name of the archive file to store filename in. If not specified,
 #          filename is added to the default archive (e.g. platform.zip). If
 #          archive == filename, filename is archived directly, not zipped.
 # direct_archive: Force a file to be archived as-is, bypassing zip creation.
 #                 NOTE: This flag will not apply if more than one file has the
 #                 same 'archive' name, which will create a zip of all the
 #                 files instead.
 # optional: List of buildtypes for which the file might not exist, and it's not
 #           considered an error.
