./main.sh, to avoid the need to fiddle with specifics of the host operating system. Using that script is strongly recommended.
This requires version 0.5.9 of webgen, and ruby 1.8 (because of a dependency on rcov). To generate these templates locally, use rvm to temporarily use ruby 1.8:
rvm use 1.8.7 bundle install webgen # Alternately, run the command `bundle exec rake auto_webgen` to regenerate the site in the background as changes are made.
