* README (The Plugin System): Removed redundant text about options and
                              files for the plugins, this is now
                              documented in the manuals for the
                              plugins.

* plugins.d/mandos-client.c (main): Remove comment which was copied
                                    from another program by mistake.
                                    Use "sscanf" instead of "strtol"
                                    to parse numbers; this uses the
                                    correct type instead of casting.
                                    Don't report errors when removing
                                    temporary directory if directory
                                    is already gone.
