Nerfed rsync
Usage of gsync:
gsync [options] sourceDir destDir
-v verbose
-f try to chmod unwriteable destination
-m XYZ write files/directories with octal mode XYZ
gsync recursively copies sourceDir to destDir, creating directories as necessary in the destination. By default the file modes are copied; -m overrides this. If the destination files are not writeable, -f will attempt to make them writeable (and then restore to the desired protection afterwards).
