'''stores authentication cookies for HTTP repositories
This extension knows how to capture Kiln authentication tokens when pushing
over HTTP. This means you only need to enter your login and password once;
after that, the FogBugz token will be stored in your home directory, allowing
pushing without a password.
If you ever need to logout of Kiln, simply run ``hg logout''
