[mercury-users] Either a documentation request or a feature request. I'm not sure which.

Say you have this directory structure

src
lib
build

where src and lib contain mercury files that you're using to build and
build is where you want to built your executable.

In the build directory you need to issue the following command
whenever you add a new mercury file

mmc -f ../src/*.m ../lib/*.m

this builds a file called Mercury.modules which the compiler users to
map module names to file names.

Now you just use mmc --make as per normal to build your application.  eg

mmc --make your_application

As mmc --make will now use the Mercury.modules file to locate the
source file for a given mercury module.
