Use \`mmc --make' to build Mercury targets.

--use-subdirs:
|

Build intermediate files in a \`Mercury' subdirectory,
|

rather than in the current directory.
|
||||
(If the current directory already contains a \`Mercury'
|

subdirectory, then this option is the default.)

--target c:
|

Compile via C, rather than going directly to assembler.

This is the default."
