// original showhide.js script
// ***************************

/*
This script was originally written by Greg Swearingen in January 2004 when the
previous method, based on Tommy Simmons script, was found not to work in later
versions of RH.
It was then found that the new script was not compatible with RH X4 or later.
Paul Symonds of Cedar Software rewrote part of it in March 2004 to make it
work with RH X4 and has made it backwards compatible.
At the same time he has amended it so that only one javascript file is required
for topics at all folder levels.
