Last change on this file since 799b60e was 799b60e, checked in by Geoffrey Thomas <geofft@mit.edu>, 12 years ago
Add the :show quickstart command. In an effort to make barnowl more self-documenting, add a ':show quickstart' command, which displays about two lines on using each protocol, a getQuickstart perl hook, and references to this command in the startup message and :help.
