#
#	. ./test-lib.sh
#	. "$TEST_DIRECTORY"/lib-httpd.sh
#	start_httpd
#
#	test_expect_success '...' '
#		...
#	'
#
#	test_expect_success ...
#
#	stop_httpd
#	test_done
#
# Can be configured using the following variables.
#
#    GIT_TEST_HTTPD              enable HTTPD tests
#    LIB_HTTPD_PATH              web server path
