[M3devel] Another CVS question: duplicate local copies

It's in the CVS/Entries files; there's a column for sticky tags.
It looks like this:

% cat m3-libs/binIO/src/CVS/Entries
/BinIO.i3/1.1.1.1/Sat Jan  5 16:32:08 2002//Trelease_branch_cm3_5_8
/BinIO.m3/1.1.1.1/Sat Jan  5 16:32:09 2002//Trelease_branch_cm3_5_8
/FastBinIO.i3/1.1.1.1/Sat Jan  5 16:32:09 2002//Trelease_branch_cm3_5_8
/FastBinIO.m3/1.1.1.1/Sat Jan  5 16:32:10 2002//Trelease_branch_cm3_5_8
/m3makefile/1.1.1.1/Sat Mar 27 11:42:57 2004//Trelease_branch_cm3_5_8
/m3overrides/1.2/Sat Jul 25 09:33:14 2009//Trelease_branch_cm3_5_8

The repository does not know about any workspaces.

You can have as many CVS workspaces with different branches and
versions as you like.

That should be no problem with CVS.
Just be careful not to mess up the CVS directories manually.
