[Checkins] SVN: z3c.pt/trunk/ In debug mode the actual source code for file templates is written out to a <filename>.source file, to make it easier to inspect it.

[Hanno Schlichting]

Log message for revision 87393:
  In debug mode the actual source code for file templates is written out to a <filename>.source file, to make it easier to inspect it.
  
  Make debug mode setting explicit in a config.py. Currently it is bound to Python's __debug__, which is False when run with -O and otherwise True.

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
+- In debug mode the actual source code for file templates is written out to
+  a <filename>.source file, to make it easier to inspect it.
+
+- Make debug mode setting explicit in a config.py. Currently it is bound to
+  Python's __debug__, which is False when run with -O and otherwise True.
+
 - Use a simplified UnicodeWrite clause for the result of _translate calls,
   as the result value is guaranteed to be Unicode.
