# Usage
#     # Parse the arguments by sourcing this script

#
# Parsed options (make)
#     -k | -keep-going | -non-stop
#     -j | -jN | -j N
#
# Parsed options (wmake)
#     -debug
#     -q | -queue
#
# Parsed options (special)
#     -l | -log | -log=FILE

Executing ${0##*/} is equivalent to

   wmake -all [OPTIONS]

With these additional options:
   -l | -log | -log=name

See
   wmake -help (or wmake -help-full)
