[pstricks] pst-user.cls: an equivalent class somewhere else?

[Hubert Lam (Publishing)]

Hi all,

I'm experimenting & trying to learn some of the intricacies that went 
into publishing the pstricks-doc manual dated December 2007, having seen 
the all three versions (1993, 2003, 2007) at

http://www.ctan.org/tex-archive/graphics/pstricks/base/doc/


I'm wondering if there is an equivalent class to pst-user.cls which was 
specifically written for the manual? I know there is a LaTeX package 
that automatically creates numbered lines for code but am unsure where 
else might I be able to find a class that generates the same layout as 
the manual. (read: I'm being lazy & don't want to manually code the 
stuff myself). I say this as pst-user.cls doesn't seem to be compatible 
with a number of other packages (like srcltx).

Thanks,

Hubert
