## Using Haml
Haml can be used in three ways:
as a command-line tool,
as a plugin for Ruby on Rails,
as a standalone Ruby module,
and as a command-line tool.
and as a standalone Ruby module.
The first step for all of these is to install the Haml gem:
gem install haml
To enable it as a Rails plugin,
then run
haml --rails path/to/rails/app
Once it's installed, all view files with the `".html.haml"` extension
will be compiled using Haml.
To run Haml from the command line, just use
haml input.haml output.html
Use `haml --help` for full documentation.
### Rails/Merb Plugin {#plugin}
To enable Haml as a Rails plugin, run
haml --rails path/to/rails/app
Once it's installed, all view files with the `".html.haml"` extension
