Usage: ${0##*/} COMMAND

Available commands are:
    init:         Initialize the git submodule - 'git submodule update --init --recursive --remote'
    add PATH:     Add a new submodule at the specified path, with the branch defaulting to 'master'. Pass branch name as third argument if different.
    del PATH:     Delete the submodule at the specified path

Examples:
    ${0##*/} info
    ${0##*/} init
    ${0##*/} update
    ${0##*/} add ../../submodule
    ${0##*/} add ../../submodule branchname
    ${0##*/} del submodule
    ${0##*/} switch submodule develop
