Pariemacs: user directory?

[Alasdair McAndrew <amca01@gmail.com>]

Hello,

I have set up pariemacs, but I can't find out how to tell it where to
find my *.gp files; that is, I can't find a variable which sets the user
directory.  I'd like to able to enter "\r myfile.gp" instead of giving
the full system name: "\r /home/amca/Programs/PariGP/myfile.gp".

Can this be done?

Thanks,
Alasdair
