+SPECIAL NOTE FOR UNIX USERS:
+============================
+
+  If you're installing this release of FreeType on a system that
+  already uses release 2.0.5 (or even an older version), you'll
+  need to perform a few special steps to ensure that everything
+  goes well:
+  
+  
+  I. Enable the TrueType bytecode hinter if you need it:
+  ------------------------------------------------------
+  
+    The TrueType bytecode interpreter is disabled in all
+    public releases of the FreeType packages for patents
+    reasons (see www.freetype.org/patents.html for more
+    details).
+    
+    However, many Linux distributions do enable the
+    interpreter in the FreeType packages (DEB/RPM/etc..) they
+    produce for their platforms. If you're using TrueType fonts
+    on your system, you'll most probably want to enable it
+    manually by doing the following:
+    
+      - open the file "include/freetype/config/ftoption.h"
+      
+      - locate a line that says:
+      
+          #undef  TT_CONFIG_OPTION_BYTECODE_ITNERPRETER
+
+      - change it to:
+
+          #define TT_CONFIG_OPTION_BYTECODE_INTERPRETER
+
+    of course, this must be done _before_ compiling the
+    library
+
+
+  II. Determine the correct installation path:
+  --------------------------------------------
+  
+    By default, the source package will install the library
+    in "/usr/local". However, many Unix distributions now
+    install the library in "/usr", since FreeType is becoming
+    a critical system component
+
+
+    If FreeType is already installed on your system, type
+    
+       freetype-config --prefix
+       
+    on the command line. This should return the installation
+    path to use below (e.g. "/usr" or "/usr/local"). Otherwise,
+    simply use "/usr"
+    
+    
+    then, to build and install the library, type:
+    
+       make setup unix CFG="--prefix=<yourprefix>"
+       make
+       make install            (as root)
+    
+    where "<yourprefix>" must be replaced by the prefix returned
+    by the "freetype-config" command.
+
+
+  III. Take care of XFree86 4:
+  ----------------------------
+  
+    Certain recent Linux distributions will install _several_
+    versions of FreeType on your system.. For example, on a
+    fresh Mandrake 8.1 system, you'll find the following files:
+    
+       /usr/lib/libfreetype.so             which links to
+       /usr/lib/libfreetype.6.1.0.so
+    
+    and:
+    
+       /usr/X11R6/lib/libfreetype.so       which links to
+       /usr/X11R6/lib/libfreetype.6.0.so
+    
+    note that these files correspond to two distinct versions of
+    the library ! It seems that this surprising issue is due to
+    the install scripts of recent XFree86 servers (from 4.1.0)
+    which irremediably install their own (dated) version of
+    the library in "/usr/X11R6/lib"
+    
+    In certain _rare_ cases, you may experience minor problems if
+    you install this release of the library in "/usr" only, namely,
+    that certain applications will not benefit from the bug fixes
+    and rendering improvements you'd expect..
+    
+    There are two good ways to deal with such nasty systems:
+    
+      - install the library _twice_, in "/usr" and in "/usr/X11R6"
+        (you'll need to do that each time you install a new
+	 FreeType release though)
+      
+      - change the link in /usr/X11R6/lib/libfreetype.so to point
+        to /usr/lib/libfreetype.so, and get rid of
+	/usr/X11R6/lib/libfreetype.6.0.so
+
+
+    The FreeType Team is not responsible for this mess, so please contact
+    either the XFree86 development team or your Linux distributor to help
+    clear this issue.., or if the above information doesn't help..
