/* wb_parse():
*
* A more or less decent rewrite of Manx' original
* wb_parse() routine which will do the following:
*
* - if open_wb_window is zero no console window
* will be opened.
*
* - if default_wb_window points to a valid string
* it will be used to open the window.
*
* - if everything fails, read the icon file,
* scan it for a "WINDOW" tool type and take
* the corresponding tool type entry string
* (somewhat primitive if compared to the Macintosh
* way of doing it...).
*
* This routine will return TRUE if it was able to
* open an output file, FALSE otherwise.
