| # * save line in hold space | |
| # * purge line | |
| # * Loop: | |
| # * append newline + lin 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> | |
