fbhelp - provide information on frame buffer selections
fbhelp displays information about the selection of frame buffer devices
available to the libfb(3) frame buffer library and the whole family of
fb programs in the BRL-CAD package, for the machine fbhelp is
run on.
The display device used by a program is taken first from the -F
framebuffer option if given, else from the environment variable
FB_FILE, or finally from whatever the default display is for that
system. fbhelp will tell you what the available choices of frame
buffers are, as well as detailed information about any options the currently
selected device may have.
