# This is a template for a script used for day-to-day size and
# performance monitoring of SQLite. Typical usage:
#
# sh run-speed-test.sh trunk # Baseline measurement of trunk
# sh run-speed-test.sh x1 # Measure some experimental change
# fossil test-diff --tk cout-trunk.txt cout-x1.txt # View chanages
#
# There are multiple output files, all with a base name given by
# the first argument:
#
# summary-$BASE.txt # Copy of standard output
# cout-$BASE.txt # cachegrind output
# explain-$BASE.txt # EXPLAIN listings
