+Purpose
+=======
+
+This extension is basically a wrapper for the FriBidi implementation
+of the Unicode Bidi algorithm. The need for such an algorithm rises
+from the bidirectional language usage  done by applications. 
+Arabic/Hebrew embedded within English is such a case.
+
+Usage
+=====
+
+ The only function used is fribidi_log2vis (logical to visual).
+     Input: 1) The Logical string.
+            2) Base direction of application - 'L' or 'R'.
+            3) The char code being used, which can be one of the following
+               constants:
+                 a) FRIBIDI_CHARSET_UTF8
+                 b) FRIBIDI_CHARSET_8859_6
+                 c) FRIBIDI_CHARSET_8859_8
+                 d) FRIBIDI_CHARSET_CP1255
+                 e) FRIBIDI_CHARSET_CP1256
+                 f) FRIBIDI_CHARSET_ISIRI_3342
+
+Note: Currently, FriBidi supports the above Character Codes alone. 
+
+      Output: A Visual string.
+
+
+Compiling
+=========== 
+1) Static - ./configure --with-fribidi=base-directory-of-FriBidi-installation-path 
+             (defaults to /usr/local).
+
+2) dl - same, just add static, to get .... --with-fribidi=static,base....
+
+Prerequisites
+=============
+1) FriBidi must be installed. Latest version can be obtained thru 
+   http://imagic.weizmann.ac.il/~dov/freesw/FriBidi.
+
+2) glib header files: glib.h and glibconfig.h.
+
+Note
+=====
+
+The function fribidi_log2vis computes three more arrays which are currently not passed back as output.
+These arrays are:
+	1) mapping from the logical to the visual sting.
+	2) mapping from the visual to the logical string.
+	3) embedding level of characters as figured out by the FriBidi algorithm.
+
+The extension needs further implementation to support this. 
+p.s. - If you don't understand this, you probably don't need it.
