biditext.so is a shared library that replaces the XDrawString function
from the libX11 library, with one that supports bidirectional printing.

This library requires Dov Grobgeld's fribidi-0.1.6 library (available from
http://imagic.weizmann.ac.il/~dov/freesw/FriBidi), which requires glib.

To compile, run the make.sh script.

To install, simply copy biditext.so to a location where any user that
might need to use it can access it (e.g, /usr/local/lib).

To use, make sure the library is loaded by the dynamic loader
(ld-linux.so), before libX11.so. This is usually done by setting the
LD_PRELOAD environment variable. For example, to run netscape on a
Mandrake 6 system (using bash), I use:

$ export LD_PRELOAD=/usr/local/lib/biditext.so
$ touch /tmp/.rev
$ /usr/lib/netscape/netscape-communicator

XDrawString changes the direction of the text only when a file /tmp/.rev
exists, so when it does not exist, it behaves, exactly like the normal
function from libX11.so. Creating or removing this file takes affect
immediately, so it can be used when using netscape to browse hebrew sites,
and moving between pages that use different directionality. 

Known Bugs:
Occasional Bus errors, usually when quiting netscape.
