Megatest

                                 overwritten by values set in config files.
  -log logfile             : send stdout and stderr to logfile
  -repl                    : start a repl (useful for extending megatest)
  -load file.scm           : load and run file.scm
  -debug N|N,M,O...        : enable debug messages 0-N or N and M and O ...

Utility
 db pgschema               : emit postgresql schema; do \"mtutil db pgschema | psql -d mydb\"

Examples:

# Start a megatest run in the area \"mytests\"
mtutil -area mytests -action run -target v1.63/aa3e -mode-patt MYPATT -tag-expr quick

# Start a contour
