# /^##/:

#   * 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>
