HELP = <<-EOH
*j* [*-@*_mark_|_mark_|*--list*|*--help*]
*j* *@*_mark_ _path_
Bookmark your favorite directories.
--list: list your current available marks.
--help: show this help message.
*j* _mark_: jumps to a mark.
*j* *@*_mark_ _path_: add a mark to path (path will be expanded).
*j* *-@*_mark_: remove a mark.
Marks must be composed of alphanumerical characters and underscores/dashes.
When you jump to a mark, you can append a trailing folder like this:
*j* _mark_/foo
and j will append foo to the resolved mark.
