This particular example is nonexistent and thus too far from reality.

I don't see any difference here. OpenGL = Open Graphics Library, so your
description is redundunt (Use Open Graphics Library graphics library).
Well, you can write 'Use Open Graphics Library', but it is again
not so much different from 'OpenGL support'.

As quite a number of other 'bad' option descriptions.

				Exactly what you are fighting against.

					The above 2 also.

Ok let's examine my 4 ports 3 of which do use OPTIONS.

OPTIONS=        GLADE "Enable libglade2 support" off \
                GLADEUI "Enable glade3 support" off

/usr/ports/devel/libglade2> cat pkg-descr 
LibGlade allows GLADE interfaces to be handled at runtime, freeing
GUI development from code development.  This allows an interface to
be changed without requiring a re-compilation.

/usr/ports/devel/glade3> cat pkg-descr 
Glade is a RAD tool to enable quick & easy development of user interfaces
for GTK+/GNOME.  It can generate the C source code needed to create
the interfaces designed within Glade's interface editor.

Any idea here how to put all these into small line of description field?
[RAD = Rapid Application Development, hope you know what GUI is]
Do these long descriptions help you?

OPTIONS=        SLGLADE "Enable slglade support (run-time)" off

/usr/ports/devel/slglade> cat pkg-descr 
SLglade is a S-Lang module that provides S-Lang bindings
for the libglade library. Used in conjunction with SLgtk,
it allows you to design your GUI with Glade (a GTK+ user interface builder),
save the interface description in a Glade XML file,
and then generate your S-Lang script's graphical interface
directly from the XML at runtime. This should reduce the time spent
developing SLgtk applications considerably, as it eliminates
the tedious job of writing interface-creation code by hand.

This is an update for Christopher Stawarz's SLglade module.

Same here, short version of pkg-descr for slglade???

OPTIONS=        FITS "Install gdk-pixbuf FITS image loader" off

Ok this seems to be what you want to have. Does it help really much?
You have to Google anyway to get some idea what is it.

I think you can understand the meaning of most of the OPTIONS if you
have some programming experience. Otherwise it is better to rely upon
maintainer's defaults.

My ideas about the subject,
