1. Copy the hhelp dir to ~/.TeXmacs/plugins
  * Should end up with:
    ~/.TeXmacs
    `-- plugins
        `-- hhelp
            |-- README
            |-- doc
            |   `-- hhelp-help.tm
            `-- progs
                |-- hhelp.scm
                `-- init-hhelp.scm
2. Start texmacs
3. Hit C-h-h. This will load hhelp-help.tm
   * This differs from the way it is actually described in init-hhelp.scm. I
     have to hold Ctrl and hit h twice. If I try C-h RELEASE C-h, as
     described, it will not work.
