+# Installs gems that are slightly broken
+# As a name it expects the name of the gem.
+# If you want to want to install a certain version
+# you have to append the version to the gem name:
+#
+# install a version of mime-types:
+# rubygems::gem{'mime-types': }
+#
+# install version 0.0.4 of ruby-net-ldap:
+# rubygems::gem{'ruby-net-ldap-0.0.4': }
+#
+# uninstall polygot gem (until no such gem is anymore installed):
+# rubygems::gem{'polygot': ensure => absent }
+#
+# uninstall ruby-net-ldap version 0.0.3
+# rubygems::gem{'ruby-net-ldap-0.0.3': ensure => absent }
+#
+# You can also set your own buildlfags, which will then install
+# the gem in question by the gem command.
+#
+# You can also enforce to use the gem command to manage the gem
+# by setting provider to `exec`.
