# 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>
