Includes is a tool that automates the maintence of makefiles by creating
a dependency list for object modules. Simply, it produces a list of all
files (.h or .inc or user specified extension, see below) included by the
source specified on the command line, and writes a line of the following
form to stdout:

foo.obj foo.lst: foo.c foo.h

Errors (included file not found, or included twice) are written to stdout,
and cause a non-zero exit code.

 
usage: includes <options> source_files

where source_files are .C or .ASM.

option	    meaning

-Dpath	    default search path for include file.  Up to 30 paths can
	    be specified.

-Ipath	    search path for include file.  Up to 30 paths can
	    be specified.

-i	    List include files from the default include directory.
	    This is /usr/include for Xenix and the directory specified
	    by the INCLUDE environment for DOS.

-lsuffix    Replace the list file suffix with "suffix" in
	    dependency lines. Up to 3 suffixes can be specified.
		For example,
		    includes -lv file.c
		 allows
		    file.obj file.lst: file.c depend1 depend2 ...
		 to become
		    file.obj file.v: file.c depend1 depend2 ...
	    The list suffix is defaulted to "lst". -l by itself
	    suppresses list file listing.

-ssuffix    Replace the object file suffix with "suffix" in
	    dependency lines. Up to 3 suffixes can be specified.
		For example,
		    includes -so file.c
		 allows
		    file.obj file.lst: file.c depend1 depend2 ...
		 to become
		    file.o file.lst: file.c depend1 depend2 ...
	    suffix is defaulted to "obj".
	    -s by itself is an error.

-Sprefix    Prepend the following prefix to object files that
	    are output as targets. Up to 3 prefixes can be specified.
		For example,
		    includes -S$(VER) *.c
		 allows
		    file.obj file.lst: file.c depend1 depend2 ...
		 to become
		    $(VER)/file.obj file.lst: file.c depend1 depend2 ...
	    No prefix is the default.

-Lprefix    Prepend the following prefix to lst files that
	    are output as targets. Up to 3 prefixes can be specified.
		For example,
		    includes -L$(VER) *.c
		 allows
		    file.obj file.lst: file.c depend1 depend2 ...
		 to become
		    file.obj $(VER)/file.lst: file.c depend1 depend2 ...
	    No prefix is the default.

-Psymbolic=string
	    Symbolic dependency. The allows makefiles to be
	    directed to a path at execution time, e.g.:
		    include -P$$(DOSROOT)=$(DOSROOT)
	    in a makefile, produces
		    file.obj: depend1 depend1 $(DOSROOT)\depend3
	    instead of
		    file.obj: depend1 depend2 ..\..\..\depend3
	    As many -P  flags as desired can be used; substitutions will
	    be performed in the order specified on the command line.

-A=ext	    permit this user-defined extension of up to 3 characters
	    for asm included files

-C=ext	    permit this user-defined extension of up to 3 characters
	    for C included files
