[Gimp-developer] questions about the cvs structure

["jay.yan" <jay.yan@xxxxxxx>]

http://www.gimp.org/devel_cvs.html  tells me that  I can get the latest 
code from cvs server via:  cvs -z3 co gimp

and also it says:
"There are also several branches in the GIMP cvs tree: the main or HEAD 
branch is GIMP 1.3 (the development version)".....

Then I tried cvs -z3 co -r gimp-1-3 gimp, of course I failed, it said: 
"no such tag gimp-1-3"

I got confused.

What will I get if I "cvs -z3 co gimp"?    is it GIMP1.3?
How can I get "main or HEAD branch"(GIMP 1.3, the development version)?

What is the structure map of the cvs? Thanks a lot!

Regards

Jay
