DevSync git wrapper for multiple repos

DevSync git wrapper for multiple repos

  1. Put the devsync.sh into some sane path, name it short to make it useful (like ~/bin/ds or /usr/local/bin/ds) and make it executable.

  2. Designate preferably an empty directory and put export DEVDIR=/path/to/your/dir into your shell environment.
