Usage: $Script [OPTIONS] TESTNAME-REGEX

Generic options:
 --help                     this help page
 --target=samba[3]|win      Samba version to target
 --testlist=FILE            file to read available tests from

Paths:
 --prefix=DIR               prefix to run tests in [st]
 --srcdir=DIR               source directory [.]
 --bindir=DIR               binaries directory [./bin]

Target Specific:
 --socket-wrapper-pcap      save traffic to pcap directories
 --socket-wrapper-keep-pcap keep all pcap files, not just those for tests that 
                            failed
 --socket-wrapper           enable socket wrapper

Samba4 Specific:
 --ldap=openldap|fedora-ds  back samba onto specified ldap server

Behaviour:
 --quick                    run quick overall test
 --one                      abort when the first test fails
 --testenv                  run a shell in the requested test environment
 --list                     list available tests
