The fvwm module debugger
FvwmDebug is spawned by fvwm, so no command line invocation will work.
The FvwmDebug captures the stream of module packets coming from fvwm, and displays them on stderr.
The FvwmDebug program, and the concept for interfacing this module to the Window Manager, are all original work by Robert Nation

During initialization, the FvwmDebug requests that fvwm dump a complete window list into its pipe. These packets are terminated with and "end Send_WindowList" message.
FvwmDebug can be invoked by inserting the line 'Module FvwmDebug' in the .fvwmrc file. This can be placed on a line by itself, if FvwmDebug is to be spawned during fvwm's initialization, or can be bound to a menu or mouse button or keystroke to invoke it later. Fvwm will search directory specified in the ModulePath configuration option to attempt to locate FvwmDebug.
There are no configuration options.
