SQLite

# A wrapper around cg_annotate that sets appropriate command-line options
# and rearranges the output so that annotated files occur in a consistent
# sorted order.  Used by the run-speed-test.tcl script.

# 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
