weston-debug - a tool for getting debug messages from compositor. weston-debug [options] [names] . ***************************************************************
weston-debug is a debugging tool which uses weston_debug_v1 interface to get the debug messages from the compositor. The debug messages are categorized into different debug streams by the compositor (example: logs, proto, list, etc.,) and the compositor requires a file descriptor to stream the messages. This tool accepts a file name or a file descriptor (not both) and any desired debug stream names from the user as command line arguments and subscribes the desired streams from the compositor by using the weston_debug_v1 interface. After the subscription, the compositor will start to write the debug messages to the shared file descriptor. If no file name or file descriptor argument is given, the tool will use the stdout file descriptor. . ***************************************************************

. B -h, --help Print the help text and exit with success.
