catclose is one of a set of Tclx message catalog related commands.
catclose ?-fail | -nofail? cathandle
Close the message catalog specified by cathandle. Normally,
errors are ignored. If -fail is specified, any errors clos-
ing the message catalog file are returned. The option
-nofail specifies the default behavior of not returning an
error. The use of -fail only makes sense if it was also
specified in the call to catopen.
