Print information on subject on stderr. An optional integer argument verbose defines the level of information which is given. The current valid subjects are:

Colors which prints information about the colors used by fvwm. This useful on screens which can only display 256 (or less) colors at once. If verbose is one or greater the palette used by fvwm is printed. If you have a limited color palette, and you run out of colors, this command might be helpful.

ImageCache which prints information about the images loaded by fvwm. If verbose is one or greater all images in the cache will be listed together with their respective reuse.

Locale which prints information on your locale and the fonts that fvwm used. verbose can be 1 or 2.

nls which prints information on the locale catalogs that fvwm used

style which prints information on fvwm styles. verbose can be 1.

bindings which prints information on all the bindings fvwm has: key, mouse and stroke bindings. verbose has no effect with this option.

infostore which prints information on all entries in the infostore, listing the key and its value. verbose has no effect with this option.
