Guardfile DSL
-------------
The Guardfile DSL consists of just three simple methods: `guard`, `watch` & `group`.
The Guardfile DSL consists of just three simple methods: `#guard`, `#watch` & `#group`.
Required:
* The `guard` method allows you to add a guard with an optional hash of options.
* The `watch` method allows you to define which files are supervised by this guard. An optional block can be added to overwrite the paths sent to the `run_on_change` guard method or to launch any arbitrary command.
* The `#guard` method allows you to add a guard with an optional hash of options.
Optional:
* The `group` method allows you to group several guards together. Groups to be run can be specified with the Guard DSL option `--group` (or `-g`). This comes in handy especially when you have a huge Guardfile and want to focus your development on a certain part.
* The `#watch` method allows you to define which files are supervised by this guard. An optional block can be added to overwrite the paths sent to the `run_on_change` guard method or to launch any arbitrary command.
* The `#group` method allows you to group several guards together. Groups to be run can be specified with the Guard DSL option `--group` (or `-g`). This comes in handy especially when you have a huge Guardfile and want to focus your development on a certain part.
