heads up: relocated recent ruby tools

[Mo Morsi]

Hey all just a heads up that the gem_dependency_checker and other
scripts recently sent out can now be found in the 'Polisher' project
here [1]. Polisher is a library and toolset aimed at providing a
reusable/extensible integration point between upstream Ruby projects and
downstream vendor resources.

The project has been organized into the standard ruby project layout and
the code refactored into reusable modules that can be leveraged to
interface with various systems in the Ruby post-upstream-publishing
workflow (for both gems and gemfile/bundler based projects).

I also migrated the gemspec from the original polisher project and
updated the gem on rubygems.org so the library and utilities are
available with a simple 'gem install polisher' (make sure to install
curl-devel and other 'curb' deps beforehand).

Also of possible interest are inflight updates to the bundler_ext
project [3] which refactor the code and add a BundlerExt#system_setup
method analogous to the Bundler#setup method. Thus a Ruby developer or
admin can even more tightly couple their Ruby and/or Rails application
to a supported platform without a large upfront module-inclusion cost.

Also be sure to checkout recent updates to the linux_admin project [4]
which has seen alot of improvements and new cool features added recently.

Hope everyone enjoys the holidays,
  -Mo
