Begin expanding upon the environment functionality with per-env config files.
Hoist config files meant to be modified by the user into a template directory, and copy them into place on "rake install".
Use nice clean absolute paths for clarity instead of jumping up and down the directory hierarchy...
Make it so OCTOPRESS_ENV is authoritative, and set things up so we're in dev mode by default when running generate/preview/etc, but production mode by default when deploying.
Update doc comments in Rakefile.
Whoops, don't force env to exist... (was breaking tests).
Switch per-env-configs over to Rakefile-templates, per the style of the times.
Add a sidebar for showing Coderwall badges.

Derived from the code provided by Coderwall, but simplified, optimized, and made to render in a way that's aesthetically pleasing in the context of Octopress.
Fix Pinboard linkrolls.
Rebase of expansions to per-environment functionality.
