Save case directories in subversion??

1. rather than trying to store the case directories for production runs on the web server alongside the run database, we could store them in a subversion repository...
2. initial case directory would need to be imported into the repository...rather than asking users to make a new directory tree for the case inside the repository and then issue 'svn import' a script could be written to handle this
3. case directories could easily be pointed to by the run database
4. case directories could easily be extracted and used to reproduce a run...any changes resulting in a new case directory could be committed back into the repository and tagged...
5. versions could be easily created, viewed and diffed using familiar svn commands
6. uploading of case directory can be done from any machine with a svn client (ie pretty much all our production machines) rather than a gzipped tar-ball from a user's own machine...
7. will require some kind of documentation to identify exactly where along the production run the new version of the case directory was used...use a ChangeLog file?...rely on subversion's documentation?
8. may want to use a separate repository from source code? "ccsm-cases"
9. requires svn client on web server to process uploaded information - this shouldn't be a problem
10. may hamper ability to migrate to a third party host if need arises

Proposed changes to create_newcase

pardon my pseudo-code...
if ( arg_for_skip_rundb != 'TRUE' ) then
   if ( no_svn_client_available  or  user/password_is_invalid ) then
      echo "unable to contact rundb to verify casename is unique"
      echo "duplicate casenames are bad - visit website to verify casename by hand"
      echo "to skip this message when running create_newcase, use arg_for_skip_rundb = 'TRUE'"
      exit
   endif
   if ( case_info_already_in_rundb ) then
      echo "casename already in use - find another casename"
      exit
   endif
   if ( casename_is_merely_reserved_in_rundb ) then
      echo "casename is reserved by $reserver - acknowledge/continue or quit?"
      if ( quit ) exit
   else
      echo "no info for casename in rundb - would you like to reserve it?"
      if ( yes ) reserve casename in rundb
   endif
endif
