I agree. This would not replace this kind of work flow.

Thank you. After a brief delay from a job change, I did compile and
install mucc today.

Here is an example of my proposed promote work flow using mucc:

General users pickup all current documents from svn://server/current

svn://server/current/doc/employee is currently a copy of
svn://server/tag/doc/employee/firstDraft

I need to make a change to the the latest employee manual, so first
I make a branch from the latest (trunk). The latest version is
slightly newer than the tag, I just have not promoted it yet.
So I will branch at latest.

$ svn copy svn://server/latest/doc/employee svn://server/branch/doc/employee/newDirective

I then switch my work area to the new branch

$ svn switch svn://server/branch/doc/employee/newDirective employee

Time to do my edits

$ ooffice2 employee/manual.odt
svn commit -m "Check point" employee
svn commit -m "New directive" employee

Switching back to the latest and merge my branch

$ svn switch svn://server/latest/doc/employee employee

$ svn merge -r27:29 svn://server/branch/doc/employee/newDirective employee

$ svn commit -m "Merged r27:29 branch/doc/employee/newDirective to latest" employee

Make a tag

$ svn copy svn://server/latest/doc/employee svn://server/tag/doc/employee/v1.1 -m "Updated with the new directive"

Now promote the svn://server/current/doc/employee to this tag
so the general employee population can now see it.

$ mucc -m "promoting new directive v1.1" rm svn://server/current/doc/employee cp 31 svn://server/tag/doc/employee/v1.1 svn://server/current/doc/employee

I hope this makes my intent a bit clearer. I have no issue continuing
to use mucc instead of a new svn command. But I still think it should
be considered as a new command since it makes things a bit easier for
non-developers to use the repository. Developers just need to keep
non-developers away from all but the svn://server/current tree.
Developers can continue to the rest of the repository as explained
in the 'recommended svn practices'.

I apologize if my use of 'latest' instead of 'trunk' has confused
anyone. Trees have branches, but they don't have tags, so why use trunk :)
