[Visualpython-users] Small vpython script suggestion

[Andrew D. <dou...@la...>]

I'm usually not working on demos, so I find the vpython's script default
working directory inconvenient.  Here's a little patch I apply to my local
copy.  If vpython gets no arguments, it starts up in the demo directory as
before.  If vpython *does* get an argument, however, it opens up the
indicated file.
