This directory contains ruby source files that define the available BUILT IN sub-commands of the `leap` executable. For example, the command: leap new Lives in lib/leap_cli/commands/new.rb However, most commands for leap_cli are defined in the platform. This directory is `leap_platform/lib/leap_cli/commands`. These files use a DSL (called GLI) for defining command suites. See https://github.com/davetron5000/gli for more information.
