Not a problem. I'm glad that diffs are now posted to -checkins. :-)

In my most complex use of ConfigParser, I had to override SECTCRE to allow
periods in the section name. Of course, that was quite interesting since
the variable is __SECTRE in 1.5.2 (i.e. I had to compensate for the
I also change OPTCRE to allow a few more charaters ("@" in particular,
which even the update doesn't do). Not a problem nowadays since those are
My subclass also defines a set() method and a delsection() method. These
are used because I write the resulting changes back out to a file. It
might be nice to have a method which writes out a config file (with an
"AUTOGENERATED BY ConfigParser.py -- DO NOT EDIT BY HAND"; or maybe
"... BY <appname> ...").
