Segmentation fault with invalid -p

[hmontenegro]

I know it is my fault for being a bit dumb, but it would be helpful if plast could deal with invalid -p, showing a nice message like "XXXX is not a valid Program Name". I get a segmentation fault when specifying (shame on me, shame on me) -p blastn.

ok, got it. We will add that feature for next release of PLAST.
