Those features are currently only available in the latest development
version of Larch. The README on the Larch GitHub page always reflects
the very latest code, not necessarily the latest release, which is
probably what caused the confusion. At some point I'll have to set up
a proper website for Larch. :)
Here's how to install the latest dev version if you'd like to use
these features:
gem sources -a http://gems.github.com
gem install rgrove-larch
Once installed, larch -v should show version 1.0.2.3, which is the
latest dev build as of this writing.
