def gopath_help_text
<<-HELPTEXT
usage: jank path

Displays additional gopaths for this directory. Paths can
be added by placing .jank files in directories with the
key 'gopath'. The gopath key can map to a string or an array
of additional gopaths. Gopaths are scanned for in this manner
up the filesystem until the user's home directory.

Gopaths specified in the .jank file can be either absolute
paths or paths relative to the directory.
