[pstricks] Newbie question on how to create an own object

[Seweryn Kokot]

Hello,

I'm very impressed with the quality of graphics and vast possibilities of
pstricks. I'm wondering if I could create a library of specific objects which I
use frequently. For example I would like to type command e.g. \psmyobject(x,y)
instead of a group of lines, triangles and cicrles which constitue the object
and (x,y) points to the upper corner of the triangle.

How to start with it?

Thank you in advance,
regards,
Seweryn Kokot
