  +#### Tool Repo (TR) Directories
   
   Origen supports setting up <code>Tool Repository</code> gem builds. This is considered an advance topic, and can
   be difficult to implement unless you are familiar with Origen's boot process and site configs, but it mentioned
  
positive.code: * If the path provided already ends with the <code>append_dot_origen</code> or <code>append_gems</code>, then those
  will not be reapplied (<code>append_dot_origen</code> and <code>append_gems</code> will be covered in the next section).
  
  ##### User Gem Directory
  
  The <code>user gem directory</code> indicates where the gems should be installed. Moving this directory around will
  change where <code>Bundler</code> places all of your gems.
  
negative.code: install directories. For additional details, please see the 
  [advanced topic on invoking Origen](<%= path "guides/advanced/invocations/#Site_Config_For_Toolset_Installations" %>).
  
  ### Configuring the Home Directory Location
  
  The previous section is an example of using the site config to manage your <code>gems</code> workspace. However,
  there's more to the workspace than just the <code>gems</code> directory.
