NAME

       weston-debug - a tool for getting debug messages from compositor.

SYNOPSIS

       weston-debug [options] [names]

DESCRIPTION

       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.
