# Find any dirty git projects in the current working directory

# USAGE:
# finddirtygit
#   Quiet mode that outputs only the project that is dirty
# finddirtygit -v
#   Verbose mode that outputs what folders are being tested
# finddirtygit -vv
#   Very verbose mode that outputs what files are dirty
