# Command Repeater | |

# For a directory tree like: | |
# | |
# MainProject/ | |
# ├── project-one | |
# ├── project-two | |
# ├── project-three | |
# └── rep # This script | |
# | |
# ... this script will run the same command in each subdirectory, | |
# as long as that subdirectory exists in the `project_dirs` variable below | |
# | |
# For example: | |
# | |
# ./rep git status | |
# | |
# ... will show, e.g.: | |
# | |
# ******************************** | |
# PROJECT: project-one | |
