### run-regtests.sh ###
  Running run-regtests.sh --help shows this information about how to use it

  Run without parameters to run all tests in the current folder (including subfolders)
    run-regtests.sh

  Provide paths to run tests from (including subfolders):
    run-regtests.sh ./tests1 ./tests2

  Parameters:
    --j <NUM>, To run varnishtest with multiple jobs / threads for a faster overall result
      run-regtests.sh ./fasttest --j 16

    --v, to run verbose
      run-regtests.sh --v, disables the default varnishtest 'quiet' parameter

    --debug to show test logs on standard ouput (implies --v)
      run-regtests.sh --debug

    --keep-logs to keep all log directories (by default kept if test fails)
      run-regtests.sh --keep-logs

    --varnishtestparams <ARGS>, passes custom ARGS to varnishtest
      run-regtests.sh --varnishtestparams "-n 10"

    --clean to cleanup previous reg-tests log directories and exit
      run-regtests.sh --clean

    --use-htx to use the HTX in tests
      run-regtests.sh --use-htx, unsets the macro \${no-htx}
      In .vtc files, in HAProxy configuration, you should use the following line
      to "templatize" your tests:

          \${no-htx} option http-use-htx

  Including text below into a .vtc file will check for its requirements
  related to haproxy's target and compilation options
    # Below targets are not capable of completing this test succesfully
    #EXCLUDE_TARGET=freebsd, abns sockets are not available on freebsd

    #EXCLUDE_TARGETS=dos,freebsd,windows

    # Below option is required to complete this test succesfully
    #REQUIRE_OPTION=OPENSSL, this test needs OPENSSL compiled in.

    #REQUIRE_OPTIONS=ZLIB|SLZ,OPENSSL,LUA

    # To define a range of versions that a test can run with:
    #REQUIRE_VERSION=0.0
    #REQUIRE_VERSION_BELOW=99.9

  Configure environment variables to set the haproxy and varnishtest binaries to use
    setenv HAPROXY_PROGRAM /usr/local/sbin/haproxy
    setenv VARNISHTEST_PROGRAM /usr/local/bin/varnishtest
  or
    export HAPROXY_PROGRAM=/usr/local/sbin/haproxy
    export VARNISHTEST_PROGRAM=/usr/local/bin/varnishtest
