/*
Script to create uniform page footer.  Created under Mozilla, modified to
work in IE6.  Used JScript lint to help with syntax and structure.  It is
much more stringent than Javascript lint. Should I take credit for this
awful kludge? Oh what the heck.  This script is copyright (c) 2007 Walter M.
Gregg (walt*w-gregg.juneau.ak.us).

May 2007: JSLint wants type coercion equality tests changes to strict
equality tests, but this fails in JavaScript 1.1 (Opera 3.62, Netscape 3.04)
and 1.0 (Internet Explorer 3 and Links 2). Change to abbreviated type
coercion compares.  that is, change if (x === 0) to if (!x), which is the
same as (x == 0); and if (x !== 0) to if (x), which is the same as (x != 0).
For strings, make an unequal(string1,string2) function that returns -1 if
string1 comes first, 0 if string1=string2, and +1 if string1 comes second.
Then replace any if (string1 === string2) constructs with if
(!unequal(string1,string2) constructs.  In the function, test for equality
by using if ((string1 <= string2) & (string1 >= string2)).  This hides the
nonstrict equality test from JSLint.
