# sed script explained:
# /^##/:
#	* save line in hold space
#	* purge line
#	* Loop:
#		* append newline + line to hold space
#		* go to next line
#		* if line starts with doc comment, strip comment character off and loop
#	* remove target prerequisites
#	* append hold space (+ newline) to line
#	* replace newline plus comments by `---`
#	* print line
# Separate expressions are necessary because labels cannot be delimited by
# semicolon; see <http://stackoverflow.com/a/11799865/1968>
