+Instructions on how to build FreeType with your own build tool
+==============================================================
+
+See  the  file `CUSTOMIZE'  to  learn  how  to customize  FreeType  to
+specific environments.
+
+
+I. Standard procedure
+---------------------
+
+  * DISABLE PRE-COMPILED  HEADERS!  This is very  important for Visual
+    C++, because FreeType uses lines like:
+
+      #include FT_FREETYPE_H
+
+    which are not correctly supported by this compiler while being ISO
+    C compliant!
+
+  * You need to add the directory `include' to your  include path when
+    compiling the library.
+
+  * FreeType 2 is made of  several components; each of them is located
+    in    a   subdirectory    of   `freetype2/src'.     For   example,
+    `freetype2/src/truetype/' contains the TrueType font driver.
+
+  * DO NOT COMPILE ALL C FILES!  Rather, compile the following ones.
+
+    -- base components (required)
+
+      src/base/ftsystem.c
+      src/base/ftinit.c
+      src/base/ftdebug.c
+
+      src/base/ftbase.c

+
+      src/base/ftmac.c        -- only on the Macintosh
+
+    -- font drivers (optional; at least one is needed)
+
+      src/bdf/bdf.c           -- BDF font driver
+      src/cff/cff.c           -- CFF/OpenType font driver
+      src/cid/type1cid.c      -- Type 1 CID-keyed font driver
+      src/pcf/pcf.c           -- PCF font driver
+      src/pfr/pfr.c           -- PFR/TrueDoc font driver
+      src/sfnt/sfnt.c         -- SFNT files support
+                                 (TrueType & OpenType)
+      src/truetype/truetype.c -- TrueType font driver
+      src/type1/type1.c       -- Type 1 font driver
+      src/type42/type42.c     -- Type 42 font driver
+      src/winfonts/winfnt.c   -- Windows FONT / FNT font driver
+
+    -- rasterizers (optional; at least one is needed for vector
+       formats)
+
+      src/raster/raster.c     -- monochrome rasterizer
+      src/smooth/smooth.c     -- anti-aliasing rasterizer
+
+    -- auxiliary modules (optional)
+
+      src/autofit/autofit.c   -- auto hinting module
+      src/cache/ftcache.c     -- cache sub-system (in beta)
+      src/gzip/ftgzip.c       -- support for compressed fonts (.gz)
+      src/lzw/ftlzw.c         -- support for compressed fonts (.Z)
+      src/bzip2/ftbzip2.c     -- support for compressed fonts (.bz2)
+      src/gxvalid/gxvalid.c   -- TrueTypeGX/AAT table validation
+      src/otvalid/otvalid.c   -- OpenType table validation
+      src/psaux/psaux.c       -- PostScript Type 1 parsing
+      src/pshinter/pshinter.c -- PS hinting module
+      src/psnames/psnames.c   -- PostScript glyph names support
+
+
+    Notes:
+
+      `ftcache.c'  needs `ftglyph.c'
+      `ftfstype.c' needs `fttype1.c'
+      `ftglyph.c'  needs `ftbitmap.c'
+      `ftstroke.c' needs `ftglyph.c'
+      `ftsynth.c'  needs `ftbitmap.c'
+
+      `cff.c'      needs `sfnt.c', `pshinter.c', and `psnames.c'
+      `truetype.c' needs `sfnt.c' and `psnames.c'
+      `type1.c'    needs `psaux.c' `pshinter.c', and `psnames.c'
+      `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
+      `type42.c'   needs `truetype.c'
+
+      Please consult the central  `include/freetype/config/ftoption.h'
+      configuration file for details on additional libraries necessary
+      for some optional features.
+
+
+  Read the file `CUSTOMIZE' in case  you want to compile only a subset
+  of  the  drivers,  renderers,   and  optional  modules;  a  detailed
+  description of the various base  extension is given in the top-level
+  file `modules.cfg'.
+
+  You are done.  In case of problems, see the archives of the FreeType
+  development mailing list.
+
+
+II. Support for flat-directory compilation
+------------------------------------------
+
+  It is  possible to  put all  FreeType 2 source  files into  a single
+  directory, with the *exception* of the `include' hierarchy.
+
+  1. Copy all files in current directory
+
+      cp freetype2/src/base/*.[hc] .
+      cp freetype2/src/raster1/*.[hc] .
+      cp freetype2/src/smooth/*.[hc] .
+      etc.
+
+  2. Compile sources
+
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
+      etc.
+
+    You don't  need to define  the FT_FLAT_COMPILATION macro  (as this
+    was required in previous releases of FreeType 2).
