On the contrary, your argument means that renaming is doomed to fail, but not
wrappers. What the wrappers do is set the path so that the external tools (GS &
Perl for now) become "visible" with their natural name. Since path is inherited,
tools called by the wrapped script will see the 3rd party tools.

Sure. That's what documentation is for :-)

The problem is, users have to know about this tool in the first place, so
documentation is needed again. Moreover, I'm not sure even the best tool can do
more than tell users to read the appropriate documentation about what to install
and how.
