/*
|
||||
* 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 is scanned for
|
||||
* any symbols that are exported via these macros:
|
||||
* EXPORT_SYMBOL(), EXPORT_SYMBOL_GPL(), &
|
||||
* EXPORT_SYMBOL_GPL_FUTURE()
|
||||
* 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
|
||||
* !Ffilename
|

* !Pfilename
