1.3     ! aaron      50: .Nm mkdep
1.1       deraadt    51: takes a set of flags for the C compiler and a list
                     52: of C source files as arguments and constructs a set of include
                     53: file dependencies which are written into the file ``.depend''.
                     54: An example of its use in a Makefile might be:
                     55: .Bd -literal -offset indent
                     56: CFLAGS= -O -I../include
                     57: SRCS= file1.c file2.c
                     58:
                     59: depend:
                     60:        mkdep ${CFLAGS} ${SRCS}
                     61: .Ed
                     62: .Pp
                     63: where the macro SRCS is the list of C source files and the macro
                     64: CFLAGS is the list of flags for the C compiler.
                     65: .Pp
                     66: The options are as follows:
                     67: .Bl -tag -width Ds
                     68: .It Fl a
                     69: Append to the output file,
                     70: so that multiple
                     71: .Nm mkdep Ns 's
                     72: may be run from a single Makefile.

1.1       deraadt    74: Write the include file dependencies to
                     75: .Ar file ,
                     76: instead of the default ``.depend''.

                     79: .Nm mkdep
                     80: to produce dependencies of the form:
                     81: .Bd -literal -offset indent
                     82: program: program.c
                     83: .Ed
                     84: .Pp
                     85: so that subsequent makes will produce
                     86: .Ar program
                     87: directly from its C module rather than using an intermediate
                     88: .Pa \&.o
                     89: module.
                     90: This is useful for programs whose source is contained in a single
                     91: module.
