Multi-tier development CVS plan

[Jeraimee Hughes]

I'll be modifying our development process here at the office from 3
tier (development->stage->production) to 4 tier
(development->stage->release->production) and I'm trying to make sure
I have the best CVS plan.

Any feedback (good and bad) would be great. I'm not sure if I'm way
off base here or if I'm starting to zero in on the best plan of
attack.

Planned:

Development Branch(s)
---------------------
 All development takes place in development branches.
 Branching from this branch is permitted for larger clients
 e.g. create a YOYO branch for custom coding for YOYO

 ----
     \DEV
      ---
         \YOYO
          \FOO

Stage Branch
------------
 This branch will be all ready development branches merged for QC and
 final testing based on dates/release schedules.

  ---------
  \DEV     \STAGE
   ---
      \YOYO
       \FOO

Release Branch
--------------
 The release branch will always be a current checkout of the same code
 on production systems, again based on dates/release schedules.

  ------------------
  \DEV     \STAGE   \RELEASE
   ---
      \YOYO
       \FOO
