Yes.  You do this for the main file in your program.  I.e. file1.m must
contain a "main" predicate for this to work.

In the "mmake file1.depend" step the Mercury compiler will look at
file1.m and work out what other files it depends on (i.e. what files
will need to be compiled and linked to make the program).
Then when you type "mmake file1" it will compile file1.m and all the
other files it discovered in the first step, and then link them into an
executable program.

This will work without writing a Mmakefile.  You only need a Mmakefile
if you want to set other variables which will affect the compilation
process, such as the "MAIN_TARGET" variable described in an earlier
post.

The Mmakefile is just a plain text file.  You can create it with any
text editor.
