Hi Paul,

It's not a legal issue.  I suspect, as you say, publishing it on the FEX 
takes care of that.  I want to say it's an ethical issue, but that's not 
it either.  I guess I'm just not comfortable doing it.  I didn't write 
it and I can't see what it's doing so I can't vouch for it.  Again, I 
don't actually have any doubt that it's benign, but I can't *prove* it.

The league you're not in is financial responsibility.  You have nothing 
to lose; TMW has lots.

The client pays TMW for MATLAB.  The client pays me to develop code with 
MATLAB.  The client pays you nothing.  If something doesn't work right 
it's my responsibility to fix it, not yours and I can't change plt.  It 
doesn't matter that you're a nice guy and are more than willing to help 
me out.  You might be busy with something else.  If I want to use third 
party code that's open and I find a problem I can fix it myself.  It's 
under my control and I'm comfortable with this.  I'm not comfortable 
with a black box.

If a client came to me and wasn't satisfied with the default plotting 
capability of MATLAB I wouldn't hesitate to recommend plt for use at the 
command line, but I won't require it for any software I write.
