+SPECIAL NOTE FOR UNIX USERS
+===========================
+
+ If you are installing this release of FreeType on a system that
+ already uses release 2.0.5 (or even an older version), you have to
+ perform a few special steps to ensure that everything goes well.
+
+
+ 1. Enable the TrueType bytecode hinter if you need it
+ -----------------------------------------------------
+
+ See the instructions in the file `TRUETYPE' of this directory.
+
+ Note that FreeType supports TrueType fonts without the bytecode
+ interpreter through its auto-hinter, which now generates relatively
+ good results with most fonts.
+
+
+ 2. Determine the correct installation path
+ ------------------------------------------
+
+ By default, the configure script installs 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
+ (e.g., `/usr' or `/usr/local'). To avoid problems of parallel
+ FreeType versions, use this path for the --prefix option of the
+ configure script.
+
+ Otherwise, simply use `/usr' (or whatever you think is adequate for
+ your installation).
+
+
+ 3. Ensure that you are using GNU Make
+ -------------------------------------
+
+ The FreeType build system _exclusively_ works with GNU Make (as an
+ exception you can use make++ which emulates GNU Make sufficiently;
+ see http://makepp.sourceforge.net). You will not be able to compile
+ the library with the instructions below using any other alternative
+ (including BSD Make).
+
+ Trying to compile the library with a different Make tool prints a
+ message like:
+
+ Sorry, GNU make is required to build FreeType2.
+
+ and the build process is aborted. If this happens, install GNU Make
+ on your system, and use the GNUMAKE environment variable to name it.
+
+
+ 4. Build and install the library
+ --------------------------------
+
+ The following should work on all Unix systems where the `make'
+ command invokes GNU Make:
+
+ ./configure --prefix=<yourprefix>
+ make
+ make install (as root)
+
+ where `<yourprefix>' must be replaced by the prefix returned by the
+ `freetype-config' command.
+
+ When using a different command to invoke GNU Make, use the GNUMAKE
+ variable. For example, if `gmake' is the command to use on your
+ system, do something like:
+
+ GNUMAKE=gmake ./configure --prefix=<yourprefix>
+ gmake
+ gmake install (as root)
+
+
+ 5. Take care of XFree86 version 4
+ ---------------------------------
+
+ Certain Linux distributions install _several_ versions of FreeType
+ on your system. For example, on a fresh Mandrake 8.1 system, you
+ can 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 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 do not benefit from the bug fixes and rendering
+ improvements you would expect.
+
+ There are two good ways to deal with this situation:
+
+ - Install the library _twice_, in `/usr' and in `/usr/X11R6' (you
+ have 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 problem, so please
+ contact either the XFree86 development team or your Linux
+ distributor to help clear this issue in case the information given
+ here doesn't help.
