Megatest

Selectors (e.g. use for -runtests, -remove-runs, -set-state-status, -list-runs etc.)
  -target key1/key2/...   : run for key1, key2, etc.
  -reqtarg key1/key2/...  : run for key1, key2, etc. but key1/key2 must be in runconfig
  -testpatt patt1/patt2,patt3/...  : % is wildcard
  -runname                : required, name for this particular test run
  -state                  : Applies to runs, tests or steps depending on context
  -status                 : Applies to runs, tests or steps depending on context
  -mode key               : load testpatt from <key> in runconfigs instead of default TESTPATT
  -tagexpr tag1,tag2%,..  : select tests with tags matching expression

Test helpers (for use inside tests)
  -step stepname
  -test-status            : set the state and status of a test (use :state and :status)
  -setlog logfname        : set the path/filename to the final log relative to the test
                            directory. may be used with -test-status
  -set-toplog logfname    : set the overall log for a suite of sub-tests
