h3. Checking an external site

You can check an external site with the rake task below.  This will crawl the site and check each link within the site, and will also check the links to external sites.  It will also check image, stylesheet and javascript references from link tags.

bc. rake cohesion:check["http://your-site-to-check.com"]

h3. Checking your local development environment

Currently you can check your local development environment the same way as you do an external, but point to your local server:

bc. rake cohesion:check["http://localhost:3000/"]


h2. Future

I intend to add the ability to check the rails app without starting the server though, which would allow you to add it to your specs.
