[p4] Problem about source tree orgnization.

[Yan Tong]

Hi,

Now I have a depot named a, and the source tree looks like (the attached
image):


*The problem:*

The code in a->b->d->src->com is the same as the code in a->b->c->src->com, so
I want to make a link between them in order not to maintain two copies of
the same code.(Also only one group is responsible for modifying the code,
other groups just use them)



What mechanism does perforce provide to support this operation?? Can branch
do this?
