    cat<<USAGE

Usage: $Script [OPTION] [dir]
       $Script [OPTION] target [dir [MakeDir]]

options:
  -s | -silent      Run make in 'silent' mode (do not echo commands)
  -a | -all         Run wmake in all subdirectories
  -h | -help        Print the usage


A general, easy-to-use make system for multi-platform development

The 'target' is a Makefile target:
    e.g., Make/linux64GccDPOpt/fvMesh.o

  or a special target:
    all       all subdirectories
    exe       build statically linked executable
    lib       build statically linked archive lib (.a)
    libso     build dynamically linked lib (.so)
    libo      build statically linked lib (.o)
    jar       build Java jar

USAGE
    exit 1

# Default make is the "make" in the path
make="make"


#------------------------------------------------------------------------------
# Parse arguments and options
