# SUMMARY:
# Run this script in the same directory as the "vdbe_profile.out" file.
# This script summarizes the results contained in that file.
#
# DETAILS:
# Compile SQLite using the -DVDBE_PROFILE option on Linux.  This causes 
# performance information about individual VDBE operations to be appended
# to the "vdbe_profile.out" file.  After content has been accumulated in
# vdbe_profile.out, run this script to analyze the output and generate a
# report.
