       This document, and the package it describes, will undoubtedly contain bugs and  other  problems.   Please
       report  such  in the category canvas of the TklibTrackers [http://core.tcl.tk/tklib/reportlist].  Please
       also report any ideas for enhancements you may have for either package and/or documentation.

       This  package  provides  utility  commands  for easier management of the tag lists associated with canvas
       items or item groups.

       The problem with the existing canvas API is that a tag list can only be set as a whole, making adding and
       removing of tags from such lists relatively complex operations reading the current  tag  list,  modifying
       it, and then writing the changed list back.

       The commands provided by this package hide all this complexity from the user.
