+.I sourcefile
+\&.\|.\|.
+.br
+.SH DESCRIPTION
+The
+.B makedepend
+program reads each
+.I sourcefile
+in sequence and parses it like a C-preprocessor,
+processing all
+.I #include,
+.I #define,
+.I #undef,
+.I #ifdef,
+.I #ifndef,
+.I #endif,
+.I #if,
+.I #elif
+and
+.I #else
+directives so that it can correctly tell which
+.I #include,
+directives would be used in a compilation.
+Any
+.I #include,
+directives can reference files having other
+.I #include
+directives, and parsing will occur in these files as well.
+.PP
+Every file that a
+.I sourcefile
+includes,
+directly or indirectly,
+is what
+.B makedepend
+calls a \fIdependency.\fP
+These dependencies are then written to a
+.I makefile
+in such a way that
+.B make(1)
+will know which object files must be recompiled when a dependency has changed.
+.PP
+By default,
+.B makedepend
+places its output in the file named
+.I makefile
+if it exists, otherwise
+.I Makefile.
+An alternate makefile may be specified with the
+.B \-f
+option.
+It first searches the makefile for
+the line
+.sp
+\& # DO NOT DELETE THIS LINE \-\^\- make depend depends on it.
+.sp
+or one provided with the
+.B \-s
+option,
+as a delimiter for the dependency output.
+If it finds it, it will delete everything
+following this to the end of the makefile
+and put the output after this line.
+If it doesn't find it, the program
+will append the string to the end of the makefile
+and place the output following that.
+For each
+.I sourcefile
+appearing on the command line,
+.B makedepend
+puts lines in the makefile of the form
+.sp
+ sourcefile.o:\0dfile .\|.\|.
+.sp
+Where \fIsourcefile.o\fP is the name from the command
+line with its suffix replaced with ``.o'',
+and \fIdfile\fP is a dependency discovered in a
+.I #include
+directive while parsing
+.I sourcefile
+or one of the files it included.
+.SH EXAMPLE
+Normally,
+.B makedepend
+will be used in a makefile target so that typing ``make depend'' will
+bring the dependencies up to date for the makefile.
+For example,
+.nf
+ SRCS\0=\0file1.c\0file2.c\0.\|.\|.
+ CFLAGS\0=\0\-O\0\-DHACK\0\-I\^.\^.\^/foobar\0\-xyz
+ depend:
+ makedepend\0\-\^\-\0$(CFLAGS)\0\-\^\-\0$(SRCS)
+.fi
+.SH OPTIONS
+The program
+will ignore any option that it does not understand so that you may use
+the same arguments that you would for
+.B cc(1).
+.TP 5
+.B \-D\fIname\fP=\fIdef\fP \fRor\fP \-D\fIname\fP
+Define.
+This places a definition for
+.I name
+in
+.B makedepend's
+symbol table.
+Without
+.I =def\|
+the symbol becomes defined as ``1''.
+.TP 5
+.B \-I\fIincludedir\fP
+Include directory.
+This option tells
+.B makedepend
+to prepend
+.I includedir
+to its list of directories to search when it encounters
+a
+.I #include
+directive.
+By default,
+.B makedepend
+only searches the standard include directories (usually /usr/include
+and possibly a compiler-dependent directory).
+.TP 5
+.B \-Y\fIincludedir\fP
+Replace all of the standard include directories with the single specified
+include directory; you can omit the
+.I includedir
+to simply prevent searching the standard include directories.
+.TP 5
+.B \-a
+Append the dependencies to the end of the file instead of replacing them.
+.TP 5
+.B \-f\fImakefile\fP
+Filename.
+This allows you to specify an alternate makefile in which
+.B makedepend
+can place its output.
+Specifying ``\-'' as the file name (i.e., \fB\-f\-\fP) sends the
+output to standard output instead of modifying an existing file.
+.TP 5
+.B \-include \fIfile\fP
+Process file as input, and include all the resulting output
+before processing the regular input file. This has the same
+affect as if the specified file is an include statement that
+appears before the very first line of the regular input file.
+.TP 5
+.B \-o\fIobjsuffix\fP
+Object file suffix.
+Some systems may have object files whose suffix is something other
+than ``.o''.
+This option allows you to specify another suffix, such as
+``.b'' with
+.I \-o.b
+or ``:obj''
+with
+.I \-o:obj
+and so forth.
+.TP 5
+.B \-p\fIobjprefix\fP
+Object file prefix.
+The prefix is prepended to the name of the object file. This is
+usually used to designate a different directory for the object file.
+The default is the empty string.
+.TP 5
+.B \-s\fIstring\fP
+Starting string delimiter.
+This option permits you to specify
+a different string for
+.B makedepend
+to look for in the makefile.
+.TP 5
+.B \-w\fIwidth\fP
+Line width.
+Normally,
+.B makedepend
+will ensure that every output line that it writes will be no wider than
+78 characters for the sake of readability.
+This option enables you to change this width.
+.TP 5
+.B \-v
+Verbose operation.
+This option causes
+.B makedepend
+to emit the list of files included by each input file.
+.TP 5
+.B \-m
+Warn about multiple inclusion.
+This option causes
+.B makedepend
+to produce a warning if any input file includes another file more than
+once. In previous versions of
+.B makedepend
+this was the default behavior; the default has been changed to better
+match the behavior of the C compiler, which does not consider multiple
+inclusion to be an error. This option is provided for backward
+compatibility, and to aid in debugging problems related to multiple
+inclusion.
+.TP 5
+.B "\-\^\- \fIoptions\fP \-\^\-"
+If
+.B makedepend
+encounters a double hyphen (\-\^\-) in the argument list,
+then any unrecognized argument following it
+will be silently ignored; a second double hyphen terminates this
+special treatment.
+In this way,
+.B makedepend
+can be made to safely ignore esoteric compiler arguments that might
+normally be found in a CFLAGS
+.B make
+macro (see the
+.B EXAMPLE
+section above).
+All options that
+.B makedepend
+recognizes and appear between the pair of double hyphens
+are processed normally.
+.SH ALGORITHM
+The approach used in this program enables it to run an order of magnitude
+faster than any other ``dependency generator'' I have ever seen.
+Central to this performance are two assumptions:
+that all files compiled by a single
+makefile will be compiled with roughly the same
+.I \-I
+and
+.I \-D
+options;
+and that most files in a single directory will include largely the
+same files.
+.PP
+Given these assumptions,
+.B makedepend
+expects to be called once for each makefile, with
+all source files that are maintained by the
+makefile appearing on the command line.
+It parses each source and include
+file exactly once, maintaining an internal symbol table
+for each.
+Thus, the first file on the command line will take an amount of time
+proportional to the amount of time that a normal C preprocessor takes.
+But on subsequent files, if it encounters an include file
+that it has already parsed, it does not parse it again.
+.PP
+For example,
+imagine you are compiling two files,
+.I file1.c
+and
+.I file2.c,
+they each include the header file
+.I header.h,
+and the file
+.I header.h
+in turn includes the files
+.I def1.h
+and
+.I def2.h.
+When you run the command
+.sp
+ makedepend\0file1.c\0file2.c
+.sp
+.B makedepend
+will parse
+.I file1.c
+and consequently,
+.I header.h
+and then
+.I def1.h
+and
+.I def2.h.
+It then decides that the dependencies for this file are
+.sp
+ file1.o:\0header.h\0def1.h\0def2.h
+.sp
+But when the program parses
+.I file2.c
+and discovers that it, too, includes
+.I header.h,
+it does not parse the file,
+but simply adds
+.I header.h,
+.I def1.h
+and
+.I def2.h
+to the list of dependencies for
+.I file2.o.
+.SH "SEE ALSO"
+cc(1), make(1)
+.SH BUGS
+.B makedepend
+parses, but does not currently evaluate, the SVR4 #predicate(token-list)
+preprocessor expression; such expressions are simply assumed to be true.
+This may cause the wrong
+.I #include
+directives to be evaluated.
+.PP
+Imagine you are parsing two files,
+say
+.I file1.c
+and
+.I file2.c,
+each includes the file
+.I def.h.
+The list of files that
+.I def.h
+includes might truly be different when
+.I def.h
+is included by
+.I file1.c
+than when it is included by
+.I file2.c.
+But once
+.B makedepend
+arrives at a list of dependencies for a file,
+it is cast in concrete.
