+module MCollective
+  # Simple module to manage vendored code.
+  #
+  # To vendor a library simply download its whole git repo or untar
+  # into vendor/libraryname and create a load_libraryname.rb file
+  # to add its libdir into the $:.
+  #
+  # Once you have that file, add a require line in vendor/require_vendored.rb
+  # which will run after all the load_* files.
+  #
+  # The intention is to not change vendored libraries and to eventually
+  # make adding them in optional so that distros can simply adjust their
+  # packaging to exclude this directory and the various load_xxx.rb scripts
+  # if they wish to install these gems as native packages.
