Hi,

This is an interesting package I've never seen before, although even being
trained in aerodynamic and flight dynamics I'm feeling almost lost with the
user interface it provides ;-).

I read avl_doc.txt and session*.txt, but still not sure how to perform trivial
tasks like computing the elevating force and the drag of a given wing
profile. It seems I'm unable to enter or supply the values of: the profile
form and angle of attack coefficients (for both elevation and drag), air
density, air speed, and the wing area in square units.

Another problem I faced while was plotting sample *.avl files (for instance: I
did ../bin/avl wing, then OPER followed by G) is that the plotted image gets
rubbered off when I move other windows over it or when I partially move that
x11plot window out of my screen and then drag it back. Is this a known
problem with Xplot11 driver? I wish the GUI has been Qt/GTK/Wx, but
nevermind ;-)

Other than that, you can remove the trailing dot from the short description as
suggested by policy and lintian, and extend the long description a little
bit.

Hi again,

This bug only appears when the XServer does not handle the BackingStore
attribute. In most installation it is off (see xdpyinfo | grep backing)
You can turn it on by adding
Option "BackingStore" "true"
to the device part of your xorg.conf.

Unfortunately it won't be easy to solve the bug as the plotlib does not
even handle the X11 mainloop (see plotlib/Xwin.c)!

If someone as ideas on how to have X11 windows to automatically redraw
itself... I have read that Xt Intrinsics can handle this, but I was not
able to find any documentation.
