That's a completely different issue.

I know lots of examples of the opposite - the same program with symlinks with different names, where the program looks to see what name it was called under, and runs slightly differently in the different cases. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
