TeX_Switcher is one small "program" for all distributions. It makes the
two changes described in an earlier message.
It is easy to change the /usr/local/texprograms link; that could be
done by lots
of programs in a multitude of ways. The harder thing to do is to
Gerben's method of setting PATH and MAN pointers. I think it is very
important to continue using his method; otherwise users who use
Gerben's distributions (surely the vast majority of us) will run into
that are hard to diagnose.
I've admitted that TeX_Switcher is a hack and welcome other programs
to do the
same thing, BUT
if an alternate program offered on this list DOES NOT use
Gerben's method to set the PATH, I'd like to request that the
announcement clearly state that it doesn't (and explain how paths

What other distributions are we talking about? I'd be happy to add
others to the program, or you
can open up TeX_Switcher yourself and see what it does. You'll find
that there are three
packages inside, one for each switch, and it will be very easy to
determine exactly how the
package makes the switch.

I just made this addition. i-Installer doesn't add it (and doesn't
destroy it either). Adding this link is very
easy; just make a symbolic link to your tex binary directory. For
Gerben's distributions, running
TeX Switcher will add the link if you installed the distribution with
GUI programs don't have to be modified at all. Users can configure
them using the link
or not as they desire.
The main reason I'm replying here is to urge that we avoid confusion
on the matter of setting
PATHS, by either using Gerben's method or making it very clear that
