###########################################
# This script runs all tests in valgrind. Configure and compile kea the way
# you want it to be tested (you should use --with-gtest or --with-gtest-source,
# however, or you get no tests). Then run this script from the top build
# directory.
#
# Note that the test isn't what you would call "production quality" (it is
# expected to be used by the kea developers, not end user) and might break,
# some ways of breaking it are known.
#
# There are two variables that modify it's behaviour.
# * VALGRIND_FLAGS are the flag passed to valgrind. There are some, hopefully
#      reasonable defaults which you can overwrite. Note that the variable is
#      used unmodified inside a sed pattern with # as a modifier, which can
#      easily break it. There was no motivation to fix this.
# * VALGRIND_FILE is the file to store the output into. Default is valgrind.log
