there are already a large number of if statements that check for IE and even IE
on a Mac. The conditional method means that we place the IE code in special
comments that are skipped unless needed and we place the NS code in sections
that are skipped by IE. the result is that we only compile the code that is
needed and there is no need to create two separate files.
I'm still researching it but am contemplating using this in my distribution and
see how it goes. basically, the less code compiled, the less memory used. It
will also reduce the amount of code compiled in NS.
