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. SEE ALSO

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 SEE ALSO
