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