[GRASS5] GRASS branching

[Markus Neteler]

Hi all,

concerning GRASS branches I would like to

 - keep the main tree as experimental (HEAD = default trunk as now,
   all modules have "exp" tag currently)
 - create stable branch from this tree by branch tagging

Advantage:
 - no changes for the developers as the tags keep unchanged
 - easier to maintain: if module is stable, "stable tag" will
   be applied, else no changes (if unstable)

Results:
 - trunk keeps as it is (no changes fro you)
 - stable version can be checked out by tag specification

Disadvantage:
 - might be unusual to have main trunk as experimental and
   stable as branch ? (I don't know)

Questions:
 - If applying a branch "stable" tag, does such a tagged module
   disappear from the main (experimental) trunk?

You comments are welcome.

I agree. Keep the number of prerequisitives as low as possible.
