Originally at 2015-01-23T14:15:09Z by Tom Rake closed at 2015-01-24T03:30:37Z (pull request) Merge of this PR will change the LIVE amber-lang.org website!!! See https://tomrake.github.io/ to preview what these changes. Things I note 1) Try Smalltalk in your browser will include the TrySmalltalk classes in the window it opens 2) Added a version to learn.html based on methods of https://github.com/amber-smalltalk/amber-website/pull/22 Please review and see if these changes are acceptable for the live site. This should close #24 Most of the changes in the PR are dependencies in bower_components.
