usage: {argv[0]} <SRCDIR> <OUTDIR>

recurses into SRCDIR, parsing each .gloss file as YAML and running the
requested parser. if a directory does not contain a '.gloss' file, or
said file's 'mode' key is missing, the mode defaults to 'copy'.

.gloss may include the following fields:
	mode:	sets the mode. may be one of 'copy', 'ignore', or
		'gloss'. if mode is 'ignore', the directory and all
		subdirectories will be skipped.
	out:	sets the output directory, relative to OUTDIR. if
		omitted, it defaults to the current path relative to
		SRCDIR.
