- * docproc is a simple preprocessor for the template files
- * used as placeholders for the kernel internal documentation.
- * docproc is used for documentation-frontend and
- * dependency-generator.
- * The two usages have in common that they require
- * some knowledge of the .tmpl syntax, therefore they
- * are kept together.
- *
- * documentation-frontend
- * Scans the template file and call kernel-doc for
- * all occurrences of ![EIF]file
- * Beforehand each referenced file are scanned for
- * any exported sympols "EXPORT_SYMBOL()" statements.
- * This is used to create proper -function and
- * -nofunction arguments in calls to kernel-doc.
- * Usage: docproc doc file.tmpl
- *
- * dependency-generator:
- * Scans the template file and list all files
- * referenced in a format recognized by make.
- * Usage: docproc depend file.tmpl
- * Writes dependency information to stdout
- * in the following format:
- * file.tmpl src.c src2.c
- * The filenames are obtained from the following constructs:
- * !Efilename
- * !Ifilename
- * !Dfilename

- * Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
- * This is a C version of syncdep.pl by Werner Almesberger.
- *
- * This program takes autoconf.h as input and outputs a directory full
- * of one-line include files, merging onto the old values.
- *
- * Think of the configuration options as key-value pairs. Then there
- * are five cases:
- *
- * key old value new value action
- *
- * KEY-1 VALUE-1 VALUE-1 leave file alone
- * KEY-2 VALUE-2A VALUE-2B write VALUE-2B into file
- * KEY-3 - VALUE-3 write VALUE-3 into file
- * KEY-4 VALUE-4 - write an empty file
- * KEY-5 (empty) - leave old empty file alone
