Test script to see whether a server supports Git interaction used by VersionPress.

1. Download or clone this repo
2. Put it under your webserver
3. Visit git-test.php in a browser

If all went fine you should see a Git version. If not, try to update the git-test.php file to point to your Git binary. For example:

$pathToGit = '/path/to/git';

This is similar to setting git-binary option in vpconfig.

If this doesn't help possibly the Symfony\Process cannot read from the process output in which case you need to debug on your end.
