PurposeThis rakefile makes it simple to package your extension and even will create signed update.rdf for you. However it needs some tuning before it could be used.

InstallationMake sure your sources are placed into svn. None of others versions controls are supported yet. Although it's easy to drop this dependency.

Make sure you have the following directory structure

root (doesn't have to be named this way)
src (doesn't have to be named this way)
content
extension_name
extension_code
skin
defaults
Rakefile
options.json
chrome.manifest.install
files.rb
mykey.pem (you going to create it later) install gems it uses

$ gem install json
$ gem install rubyzipMake new cert

$ openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout ../mykey.pem -out mycert.pemcreate options.json and put configurations inside. Example
