NAME
  gitup - extended git update utility

SYNOPSIS
  gitup [options] [directory]

DESCRIPTION
  gitup is an extended git update utility that updates all git repositories
  within a single folder. For example if we have 3 git repositories within a
  folder named 'temp', then gitup can recursivly update the repositories
  within the 'temp' folder.

OPTIONS
  -u, --update [dir]       - Update to the latest copy of [dir]
  -U, --updatesub [dir]    - Update to the latest copy of [dir] inc submodules
  --upgradesub [dir]       - Upgrade submodules to latest release from source

  -v, --verbose            - Enable Verbose output
  -V, --version            - Display program version and exit
  -h, --help               - Display help message and exit

NOTES
  If verbose is enabled it must be the first argument.
  Example: Verbose update of directory 'temp'. Direcotry can have trailing "/"
    $ gitup -vu temp
    $ gitup -v -u temp
    $ gitup -v --update temp
