how to restore removed branch

[Yan, Rong (R.)]

Hello,

My name is Rong. I am working in Ford Motor Company. We are
using CVS as a revision control tool  for our software development.
I made a mistake yesterday: when I tried to remove a branch from
a file under certain dirctory, I did it under graph mode. So CVS removed
this branch from every file under this directory. This branch is the 
main branch for our project. We have to restore it to every file under
this directory and keep the original revision history. Please tell me how 
could we do this? Thanks.

Regards,

Rong

P.S. 


This is an example of the our file with correct history graph inside CVS:

 <<...OLE_Obj...>> 


This is an example of our files which I removed the main branch
'scvsp_v1' accidentally : 


 <<...OLE_Obj...>>
