[Halld-offline] GlueX software on GitHub, trial port

[Mark Ito]

Folks,

I've done a trial port of hdds and sim-recon from our Subversion 
repository to GitHub. These are just for fooling around for now; think 
of them as scratch copies of the repositories. Our Subversion repository 
is not and will not be affected by these git repositories.

If you are interested in messing around, the git repositories are 
available at

   https://github.com/markito3/hdds.git
   https://github.com/markito3/sim-recon.git

To get a local copy of a repository, you say

   git clone <URL>

at the shell command line, where <URL> is one of the two above. Git must 
be installed on your machine, of course. A new directory will appear in 
the working directory. Note that this gives you not only the latest 
"trunk" version of the files, but all of its history and the most recent 
tags (I went back 5 years) on your local disk; that is just what git 
always does. The magic is the .git directory in the top-level directory.

There is no way to push changes back upstream with this initial set-up. 
For now, that lack is a "feature". Also note that I am doing this from 
my personal GitHub account for now, another "feature". Baby steps...

P. S. There are lots of resources for learning about git on the web. One 
I found useful is http://git-scm.com/doc .
