# Run this script in an open Fossil checkout at the top-level with a
# fresh build of Fossil itself.  This script will run fossil on hundreds
# of different web-pages looking for memory allocation problems using
# valgrind.  Valgrind output appears on stderr.  Suggested test scenario:
#
#     make
#     tclsh valgrind-www.tcl 2>&1 | tee valgrind-out.txt
#
# Then examine the valgrind-out.txt file for issues.
