### 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 vtest 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 vtest 'quiet' parameter

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

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

    --vtestparams <ARGS>, passes custom ARGS to vtest
      run-regtests.sh --vtestparams "-n 10"

    --type <reg tests types> filter the types of the tests to be run, depending on
      the commented REGTESTS_TYPE variable value in each VTC file.
      The value of REGTESTS_TYPE supported are: default, slow, bug, broken, devel
      and experimental. When not specified, it is set to 'default' as default value.

      run-regtest.sh --type slow,default

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

  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 successfully
    #EXCLUDE_TARGET=freebsd, abns sockets are not available on freebsd

    #EXCLUDE_TARGETS=dos,freebsd,windows

    # Below option is required to complete this test successfully
    #REQUIRE_OPTION=OPENSSL, this test needs OPENSSL compiled in.
    #REQUIRE_OPTIONS=ZLIB|SLZ,OPENSSL,LUA

    #REQUIRE_SERVICE=prometheus-exporter
    #REQUIRE_SERVICES=prometheus-exporter,foo

    # 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 vtest binaries to use
    setenv HAPROXY_PROGRAM /usr/local/sbin/haproxy
    setenv VTEST_PROGRAM /usr/local/bin/vtest
    setenv HAPROXY_ARGS "-dM -de -m 50"
