Usage: compass [options] [project]

Description:
|
|
||||||
The compass command line tool will help you create and manage the stylesheets for your project.
|
|
||||||
|
|
||||||
To get started on a stand-alone project based on blueprint:
|
|
||||||
|
|
||||||
compass -f blueprint my_compass_project
|
|
||||||
|
|
||||||
When you change any sass files, you must recompile your project using --update or --watch.

Usage: compass [options] [project]
|
||||||
|
|
||||||
|
Description:
|
||||||
|
The compass command line tool will help you create and manage the stylesheets for your project.
|
||||||
|
|
||||||
|
To get started on a stand-alone project based on blueprint:
|
||||||
|
|
||||||
|
compass -f blueprint my_compass_project
|
||||||
|
|
||||||
|
When you change any sass files, you must recompile your project using --update or --watch.
