And I'm using a similar setup to the hourly commit cron job of Rainer's
but with the following script so it removes deleted files too.  This
works over multiple org repositories.

,----[ org-git-sync.sh ]
| #!/bin/sh
| # Add org file changes to the repository
| REPOS="org doc.norang.ca www.norang.ca"
| 
| for REPO in $REPOS
| do
|     echo "Repository: $REPO"
|     cd ~/git/$REPO
|     # Remove deleted files
|     git ls-files --deleted -z | xargs -0 git rm >/dev/null 2>&1
|     # Add new files
|     git add . >/dev/null 2>&1
|     git commit -m "$(date)"
| done
`----

,----[ crontab entry ]
| 0 * * * * ~/bin/org-git-sync.sh >/dev/null
`----

If I want to manually update I just run the org-git-sync.sh script at
the shell prompt.  Usually I do that when moving files to/from my laptop
- so I commit all the changes to the repos and then push/pull the
commits.

I've also added a .gitignore file to skip files created by exporting

,----[ .gitignore ]
| *.html
| *~
| .#*
| \#*\#
| *.txt
| *.tex
| *.aux
| *.dvi
| *.log
| *.out
| *.ics
| *.pdf
`----

so files created by exporting are not automatically added to the repo.
I can still explicitly add .pdf files as attachments if necessary so
that they become tracked.
