 this  is just  a space-delimited  list of  main links.  the
 first part should  contain the URL to link  to, relative to
 the root of the generated site.

 for instance, if you have a file in src/stories/a-story.md,
 you would write /src/stories/a-story.html.

 note that URLs cannot contain spaces! also, lines beginning
 with a space are treated as comments and are ignored by the
 parser.
