-.SH DESCRIPTION
-The \fIglforestfire\fP program draws an animation of sprinkling fire-like 3D triangles in
-a landscape filled with trees.
-.SH OPTIONS
-.I glforestfire
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window. This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-install
-Install a private colormap for the window.
-.TP 8
-.B \-visual \fIvisual\fP\fP
-Specify which visual to use. Legal values are the name of a visual class,
-or the id number (decimal or hex) of a specific visual.
-.TP 8
-.B \-fps
-Display the current frame rate, CPU load, and polygon count.
-.TP 8
-.B \-trees \fInumber_of_trees\fP\fP
-Specify how much trees are drawn in the landscape.
-.TP 8
-.B \-count \fInumber_of_particles\fP\fP
-Specify how much fire particles are drawn. A very special case is 0
-wich means that you get
-.B rain
-!
-.TP 8
-.B \-size \fIviewport_size\fP\fP
-Viewport of GL scene is specified size if greater than 32 and less than screensize. Default value is 0, meaning full screensize.
-.TP 8
-.B \-texture
-Show a textured ground and the trees. This is the default.
-.TP 8
-.B \-no\-texture
-Disables texturing the landscape. This implies that no trees are drawn.
-.TP 8
-.B \-shadows
-Show a shadow for each particle on the ground. This is the default.
-.TP 8
-.B \-no\-shadows
-Disables the drawing of the shadows.
-.TP 8
-.B \-fog
-Show a fog in the distance.
-.TP 8
-.B \-no\-fog
-Disables the fog. This is the default.
-.TP 8
-.B \-wander
-Move the observer around the landscape. This is the default.
-.TP 8
-.B \-no\-wander
-Keep the fire centered on the screen.
-.TP 8
-.B \-trackmouse
-Let the mouse be a joystick to change the view of the landscape.
-This implies
-.I \-no\-wander.
-.TP 8
-.B \-no\-trackmouse
-Disables mouse tracking. This is the default.
-.TP 8
-.B \-wire
-Draw a wireframe rendition of the fire: this will consist only of
-single-pixel lines for the triangles.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
