install.me makes it so mhonarc itself has the proper path to perl
and that it can automatically find its libraries when it starts.
It does *not* modify your shell environment in any way.

BAD IDEA.  Puting '.' in your path is a local security risk.  Whatever
bin install pathname you specified when running install.me, add that
pathname to your PATH environment variable.  You typically do that
in your .bashrc file in your home directory:

  export PATH=${PATH}:/path/installed/mhonarc/into/here

Always have full pathnames in your PATH.

Any changes you make to your .bashrc will require that you restart
your current shell process (i.e. login and logoff) or explicitly source
the file:

  . $HOME/.bashrc

Anytime I run a program that is located in the current working directory,
I always use

  ./program-name ...

I leave it as an exercise for the reader on why have '.' in your
search path is a security risk :-)
