 16.3.73 source
 --------------
 
  -- Command: source file
      Read FILE as a configuration file, as if its contents had been
      incorporated directly into the sourcing file.  Unlike 'configfile'
      (⇒configfile), this executes the contents of FILE without
      changing context: any environment variable changes made by the
      commands in FILE will be preserved after 'source' returns, and the
      menu will not be shown immediately.
