[PEPPo] attempt at a repository

[Arne Freyberger]

Eric and Alex,
     Perhaps this is a distraction, but it might save us from some 
headaches once the  changes/edits start coming fast a furious.  I 
created a "git" repository on the Jlab CUE machine.  Everyone in the 
positron group should have access.  Git is available for 
Linux/MacOS/Windows so everyone should be able to work with this.

Here is how to get latest version of the proposal (assuming linux 
command prompt):

   1. git clone
      ssh://username@ifarml1/u/group/positron/repository/proposal.git
         1. Outside the firewall, you'll have to set up a tunnel
         2. this will create a directory called "proposal" in the
            directory that you executed the command
   2. cd proposal
   3. make changes
   4. git add newfile1.xxx newfile2.xxx
         1. "git add" adds new files to  your copy of the repository
   5. git commit  newfile1.xxx -m "new image for the summary section"
   6. git commit  newfile2.xxx -m "another new image"
         1. Use this command  to "commit" new files to your repository
   7. git commit -a -m "updated section 666 to reflect the actual reality"
         1. this will commit all the existing files that have been
            changed to your repository
   8. git push origin master
         1. This command actual pushes your changes back to JLAB repository

Note:   git's strength is that everyone gets there own local copy and 
all "git add" and "git commit" are held locally until the user is ready 
to share his/her work.  So please use git add and git commit  as much as 
possible.   A firewall/network connect is only needed for steps 1 & 8,   
so you can make use of git version control even when not connected to 
the network.

     Working in an existing clone of repository the following commands 
might be helpful:

   1. git pull
         1. will pull in and changes from the JLAB repository
   2. git status
         1. will give you the status of your local repository, any
            changed or new files, this does not say anything about your
            files and the repository

I hope this is helpful.  I'll work on a wiki page...let me know what 
does and does not work.

Arne
