CHANGES

- Symbol Tables and Templates are now first-class objects in their own
  right (classes 'SymbolTable' and 'Template' respectively).  This
  means API will not be compatible with programs built using previous
  versions of 'tconfpy'.  You must now pass/receive objects of the
  appropriate type rather than just dictionaries as was previously the
  case.

- The 'RetObj' object has been removed.  Objects of type 'SymbolTable'
  are now returned.

- Significant internal code resturcturing to encasulate parse-related
  data structures into the 'Symbol Table' object.  This eliminated
  most of the global variables.

- Template variables previously required a right hand side when
  instantiated.  It is now possible to have a construct like
  "TemplateVariable=" in the configuration file.  In that case, the
  variable is brought into existence with the default value found in
  its template.  This means the default value must be one of the
  entries in the 'LegalVals' field of that variable's descriptor.  If
  it is not, the user will be *required* to enter a right hand side in
  the configuration file. (Because the default will be illegal in this
  case and thus not accepted by 'tconfpy'.)
  

NEW FEATURES

- Added the 'CallingProgram' API keyword parameter.  This allows the
  calling program to change the program name embedded in every message
  produced during the parse.




WHATSNEW For 'tconfpy' 1.185    (Sun May  2 03:07:05 CDT 2004)
----------------------------------------------------------------------

BUG FIXES

- The content of literal blocks found within False conditional
  blocks was being reported as a syntax error.  This was 
  benign, but annoying.  Now all text within literal blocks is
  not syntax checked, whether or not the enclosing block is True.


WHATSNEW For 'tconfpy' 1.184    (Tue Apr 27 18:54:11 CDT 2004)

Added support for Variable Templates.
Added the 'ReturnPredefs' API option.


WHATSNEW For 'tconfpy' 1.181    (Sat Apr 24 15:49:13 CDT 2004)

First public release of the program.
