.SH NAME
m2mm \- Modula-2 makefile generator
.SH SYNOPSIS
\fBm2mm\fP [ \fB-I\fPdir \fB-L\fPdir \fB-l\fPlibrary \fB-M\fPflags \fB-C\fPcompiler \fB-S\fPsuffix ] file ...
.SH DESCRIPTION
.I M2mm
is a makefile generator and fast syntax checker for Modula-2 programs.
The makefile is produced on standard output.
.I M2mm
will generate rules to produce an object file
for every module used in the argument files.
In addition, it will generate a rule to make a program, for each of the
program modules given as argument.
Using 
.IR make (1)
without an argument will make all these programs.
.PP
In the makefile, the variables \fBMOD\fP, \fBM2FLAGS\fP, \fBIFLAGS\fP, \fBLIBS\fP, and
\fBSUFFIX\fP will be defined.
The generated rules have the following form:
.IP "\fIname\fP.$(SUFFIX): ..."
.br
$(MOD) -c $(M2FLAGS) $(IFLAGS) \fIname\fP.mod
.PP
.I M2mm
recognizes the following options:
.IP \fB-I\fP\fIdir\fP
Add \fIdir\fP to the list of directories where definition modules are 
looked for. Also add the flag to \fBIFLAGS\fP.
The default value for \fBIFLAGS\fP is empty.
.IP \fB-L\fP\fIdir\fP
Add \fIdir\fP to the list of directories where definition modules are 
looked for. Also add the corresponding \fB-I\fP flag to \fBIFLAGS\fP.
The difference with the \fB-I\fP flag is, that the \fB-L\fP directories are considered
interfaces to libraries, and thus no rules are generated using or creating
object files for modules found in these directories. Instead, the user is
expected to add a library to the \fBLIBS\fP macro, using the \fB-l\fP flag.
.IP \fB-M\fP\fIflags\fP
Set \fBM2FLAGS\fP to \fIflags\fP.
.IP \fB-C\fP\fIcompiler\fP
Set \fBMOD\fP to \fIcompiler\fP.
The default value for \fBMOD\fP is "ack" (for the time being).
.IP \fB-l\fP\fIlibrary\fP
Add \fIlibrary\fP to the \fBLIBS\fP macro. This macro is initially empty,
and is passed to the loader.
.IP \fB-S\fPsuffix
Set \fBSUFFIX\fP to \fIsuffix\fP.
The default suffix is "o".
