Usage: dependencies.py [options]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -r ROOT, --root=ROOT  The root of the subtree with dependency information
                        (default: ".").
  -s SUFFIX, --suffix=SUFFIX
                        The suffix of the files with dependency information
                        (default: ".d").
  -o FILE, --output=FILE
                        The output is written to this file (default: stdout).
  --strip-prefix=PREFIX
                        Strips PREFIX from all filenames if matching. The root
                        directory is always stripped. Useful for out-of-source
                        builds or weird automounters. Can be given multiple
                        times. The prefixes are tried in the order of their
                        appeareance on the command line. The first match
                        (except the root directory) stops processing of the
                        remaining prefixes.
  --verbose             Enables the verbose mode.

  Filter options:
    The following options control filters to postprocess the dependency
    graph. All filter options can be given multiple times and are applied
    in the order of their appearance on the command line.

    --filter-contract-directories
                        Replaces all nodes representing files in a particular
                        directory by a single node for that directory.
    --filter-drop-absolute-paths
                        Removes all nodes representing files with an absolute
                        path.
    --filter-drop-loops
                        Removes all loops, i.e., edges where source and target
                        are equal.
    --filter-source=REGEX
                        Removes all edges with sources not matching REGEX.
    --filter-target=REGEX
                        Removes all edges with targets not matching REGEX.
    --filter-source-and-target=REGEX
                        Removes all edges with sources and targets not
                        matching REGEX.
    --filter-dependencies=REGEX
                        Removes all nodes not reachable from nodes matching
                        REGEX by a forward graph traversal, i.e., only the
                        dependencies of nodes matching REGEX remain.
    --filter-reverse-dependencies=REGEX
                        Removes all nodes not reachable from nodes matching
                        REGEX by a backward graph traversal, i.e., only the
                        nodes depending on nodes matching REGEX remain.
    --filter-generic=LAMBDA
                        Applies the given lambda function to all edges of the
                        graph. The lambda function must accept two string
                        arguments. It is called for all edges with the source
                        and target nodes as arguments. It must return None,
                        which removed the edge, or a pair of two strings. In
                        the latter case, this pair is interpreted as snew
                        ource and target node of the edge. For example,
                        "lambda s, t: (t, s)" reverts the direction of all
                        edges.
