# Perl script to analyze the log output from xpcom and print
# the results in html.
#
# To get the xpcom log output to a file say xpcom.log:
# setenv NSPR_LOG_MODULES nsComponentManager:5
# setenv NSPR_LOG_FILE xpcom.log
# ./mozilla
# <quit>
#
# To get registry (used to figure out progid mappings)
# ./regExport component.reg > registry.txt
# Usage:
#
# a) To get simple output
# cat xpcom.log | perl xpcom-log-analyze.pl > xpcom-log.html
#
# b) To get all possible cid->progid mappings filled in
# cat xpcom.log registry.txt | perl xpcom-log-analyze.pl > xpcom-log.html
