Subject: Exposed the mutli-overlay functionality in the ruby bindings.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a2cda6dcf9df83aa60a94456fb576444716432b8;p=thirdparty%2Fstrongswan.git

Exposed the mutli-overlay functionality in the ruby bindings.

Overlays can be added to individual guests (which overlays exactly the		supplied directory) or to all guests (which overlays a subdirectory with the guest's name to each guest).

The template functionality is provided as before.
