  # Adds a Ruby Gem to the $LOAD_PATH.  Before a Gem is loaded, its
  # required Gems are loaded.  If the version information is omitted,
  # the highest version Gem of the supplied name is loaded.  If a Gem
  # is not found that meets the version requirement and/or a required
  # Gem is not found, a Gem::LoadError is raised. More information on
  # version requirements can be found in the Gem::Version
  # documentation.
  #
  # The +gem+ directive should be executed *before* any require
  # statements (otherwise rubygems might select a conflicting library
  # version).
  #
  # You can define the environment variable GEM_SKIP as a way to not
  # load specified gems.  you might do this to test out changes that
  # haven't been intsalled yet.  Example:
  #
  #   GEM_SKIP=libA:libB ruby-I../libA -I../libB ./mycode.rb

  # gem:: [String or Gem::Dependency] The gem name or dependency
  #       instance.
  #
  # version_requirement:: [default=">= 0.0.0"] The version
  #                       requirement.
  #
  # return:: [Boolean] true if the Gem is loaded, otherwise false.
  #
  # raises:: [Gem::LoadError] if Gem cannot be found, is listed in
  #          GEM_SKIP, or version requirement not met.
