       source - Evaluate a file or resource as a Tcl script

       source fileName

       source -rsrc resourceName ?fileName?

       source -rsrcid resourceId ?fileName?

       This command takes the contents of the specified file or resource and passes it to the Tcl
       interpreter as a text script.  The return value from source is the  return  value  of  the
       last command executed in the script.  If an error occurs in evaluating the contents of the
       script then the source command will return that error.  If a  return  command  is  invoked
       from  within the script then the remainder of the file will be skipped and the source com-
       mand will return normally with the result from the return command.

       The end-of-file character for files is '\32' (^Z) for all platforms.  The  source  command |
       will  read  files  up  to this character.  This restriction does not exist for the read or |
       gets commands, allowing for files containing code and data segments (scripted  documents). |
       If you require a ``^Z'' in code for string comparison, you can use ``\032'' or ``\u001a'', |
       which will be safely substituted by the Tcl interpreter into ``^Z''.

       The -rsrc and -rsrcid forms of this command are only  available	on  Macintosh  computers.
       These  versions of the command allow you to source a script from a TEXT resource.  You may
       specify what TEXT resource to source by either name or id.  By default  Tcl  searches  all
       open  resource  files,  which include the current application and any loaded C extensions.
       Alternatively, you may specify the fileName where the TEXT resource can be found.
