## zevents.awk -- analyse Zope logs
##
## Parse Zope-Events logfile-data and extract fields. Output 
## as CSV or SQL format.
##
## (c) 2006 Uli Fouquet
##
## Syntax: awk [-v SQL=0|1] [-v TRACEBACK=0|1] -f zevents.awk <input-file>
##
## Options:
##
## -v SQL if SQL is set, SQL output will be generated.
##              Othwewise you will get CSV output (default:0)
##
## -v TRACEBACK if this option is set to '0', tracebacks will
##              not be included in output (default: 1)
