       makeppclean [ -b ] [ -l ] [ -R ] [ -r ] [ -v ] [ path ... ]

       mppc [ -b ] [ -l ] [ -R ] [ -r ] [ -v ] [ path ... ]

       Makeppclean efficiently removes files that were knowingly generated through makepp.  For
       each path, if path is not a directory and was known to be generated by makepp by virtue of
       having a build info file with a matching signature, then remove path and its build info
       file; and if path is a directory, do the same for every file in path, and then remove the
       build info directory below path.  path defaults to ".".

       The traditional approach to removing generated files is to create a "clean" target in your
       makefiles whose action is to remove all of the targets.  This approach has some
       fundamental limitations:

       • It requires that all the relevant makefiles be loaded before cleaning. This can take
         quite a while.

       • If the clean target in one makefile depends on the clean target in another makefile,
         then it is possible that a file that must be built in order to load one of the makefiles
         (e.g. because of a prebuild statement) has already been built and cleaned by the time it
         needs to be built again.  Makepp wisely fails in this situation, rather than potentially
         building the same file many times during the course of a single build.

       Provided that your intention is to remove all the generated files without regard for which
       makefile (if any) currently generates them, then these limitations are avoided by using
       makeppclean.

OPTIONS

       -A filename
       --args-file=filename
       --arguments-file=filename
           Read the file and parse it as possibly quoted whitespace- and/or newline-separated
           options.

       -b
       --build-cache-links
       --only-build-cache-links
           Remove only links or files from a build cache.

       -d
       --empty-directories
           Remove directories that became empty after removing their content.  Since directories
           are not usually created by rules, makepp does not keep track of which one it created.
           Therefore this applies to those, where makepp created something, whether the directory
           was created manually or automatically.

       -?
       -h
       --help
           Print out a brief summary of the options.

       -k
       --keep-src-info
       --leave-src-info
           Leave the build info directory below each named directory.

       -l
       --log
       --only-logs
           Remove only the raw logfiles, which can be many in case of traditional recursion.

       -m
       --meta
       --only-meta
       --makepp
           Remove only the meta information subdirectories.

       -R
       --repository-links
       --only-repository-links
           Remove only links pointing to a repository.

       -r
       --recurse
       --recursive
           Descend each named directory recursively.  Symbolic links are not followed.

       -v
       --verbose
           Enable verbose output to STDERR.

       -V
       --version
           Print out the version number.

ENVIRONMENT

       Makeppclean looks at the following environment variable:

       $MAKEPPCLEANFLAGS
           Any flags in this environment variable are interpreted as command line options before
           any explicit options.  Quotes are interpreted like in makefiles.
