Sorry, but the prolog interpreter is historically always named pl.  And
a name clash like this, which provides *entirely* different tools using
the same name shouldn't be solved on a "first come, first serve" base.
This isn't the same situation as with ksh and pdksh or ash and bash.
So, no, I won't change the SWI-Prolog package to create /usr/bin/pl
only if it doesn't exist.  What's the problem having ploticus being named
