NAME

     rcorder -- print a dependency ordering of interdependent files

SYNOPSIS

     rcorder [-k keep] [-s skip] file ...

DESCRIPTION

     rcorder is designed to print out a dependency ordering of a set of interdependent files.  Typically it is used to find an execution sequence
     for a set of shell scripts in which certain files must be executed before others.

     Each file passed to rcorder should be annotated with special lines (which look like comments to the shell) which indicate the dependencies
     the files have upon certain points in the sequence, known as ``conditions'', and which indicate, for each file, which ``conditions'' may be
     expected to be filled by that file.

     Within each file, a block containing a series of ``REQUIRE'', ``PROVIDE'', ``BEFORE'' and ``KEYWORD'' lines should appear.  The format of the
     lines is rigid.  Each line must begin with a single ``#'', followed by a single space, followed by ``PROVIDE:'', ``REQUIRE:'', ``BEFORE:'',
     or ``KEYWORD:''.  No deviation is permitted.  Each dependency line is then followed by a series of conditions, separated by whitespace.  Mul-
     tiple ``PROVIDE'', ``REQUIRE'', ``BEFORE'' and ``KEYWORD'' lines may appear, but all such lines must appear in a sequence without any inter-
     vening lines, as once a line that does not follow the format is reached, parsing stops.

     The options are as follows:

     -k      Add the specified keyword to the ``keep list''.  If any -k option is given, only those files containing the matching keyword are
	     listed.

     -s      Add the specified keyword to the ``skip list''.  If any -s option is given, files containing the matching keyword are not listed.

      An example block follows:

	   # REQUIRE: networking syslog
	   # REQUIRE: usr
	   # PROVIDE: dns nscd

     This block states that the file in which it appears depends upon the ``networking'', ``syslog'', and ``usr'' conditions, and provides the
     ``dns'' and ``nscd'' conditions.

     A file may contain zero ``PROVIDE'' lines, in which case it provides no conditions, and may contain zero ``REQUIRE'' lines, in which case it
     has no dependencies.  A file containing no ``PROVIDE'', ``REQUIRE'', or ``BEFORE'' lines may be output at an arbitrary position in the depen-
     dency ordering.

     There must be at least one file with no dependencies in the set of arguments passed to rcorder in order for it to find a starting place in
     the dependency ordering.

DIAGNOSTICS

     rcorder may print one of the following error messages and exit with a non-zero status if it encounters an error while processing the file
     list.

     Requirement %s has no providers, aborting.  No file has a ``PROVIDE'' line corresponding to a condition present in a ``REQUIRE'' line in
     another file.

     Circular dependency on provision %s, aborting.  A set of files has a circular dependency which was detected while processing the stated con-
     dition.

     Circular dependency on file %s, aborting.	A set of files has a circular dependency which was detected while processing the stated file.

NAME

       mkdep - generate dependency list from a C program

SYNOPSIS

       mkdep [-a] [-f depend_file] [-p] [cc_options] file...

       The mkdep command generates a dependency list file from a C source program.

OPTIONS

       Causes mkdep to append its output to the end of the dependency file instead of creating a new dependency file.  If the dependency file does
       not exist, mkdep creates it.  Specifies a name for the dependency file; overrides the default file name Inhibits mkdep from  appending  the
       suffix to the names of object files listed in the output.

DESCRIPTION

       The  mkdep  command uses cc(1) to compile a list of dependency files required to build the named C program file or files.  The list is for-
       matted so that it is suitable for inclusion into a makefile for make(1).  Duplicate dependency listings for a given  program  are  included
       only once in the output.

       You can specify C compiler options by including them in the command line; mkdep passes all unrecognized options through to the compiler.

       By default, mkdep writes to a file named -f option to specify an alternative output file name.

EXAMPLES

       The following example illustrates the use of mkdep with the -p option:

       % cat hello.c #include <stdio.h>

       main() {

	       printf("%s0","Hello  World!");  }  %  mkdep  -p	-f  hello.depend  hello.c  % cat hello.depend hello:  hello.c /usr/include/stdio.h
       /usr/include/standards.h   hello:    /usr/include/sys/types.h   /usr/include/standards.h    hello:     /usr/include/mach/machine/vm_types.h
       /usr/include/sys/limits.h   hello:    /usr/include/standards.h	/usr/include/machine/machlimits.h   hello:    /usr/include/sys/syslimits.h
       /usr/include/float.h hello:  /usr/include/standards.h /usr/include/fp_class.h hello:  /usr/include/machine/machtime.h
