+Due to our use of `libtool' to generate and install the FreeType 2
+libraries on Unix systems, as well as other historical events, it is
+generally very difficult to know precisely which release of the font
+engine is installed on a given system.
+
+This file tries to explain why and to document ways to properly detect
+FreeType on Unix.
+
+
+1. Version and Release numbers
+------------------------------
+
+For each new public release of FreeType 2, there are generally *three*
+distinct `version' numbers to consider:
+
+ * The official FreeType 2 release number, like 2.3.1 or 2.4.10.
+
+ * The libtool (and Unix) specific version number, like 13.0.7. This
+ is what `freetype-config --version' returns.
+
+ * The platform-specific shared object number, used for example when
+ the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
+
+The platform-specific number is, unsurprisingly, platform-specific and
+varies with the operating system you are using (several variants of
+Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even
+for simple tests.
+
+The libtool-specific number does not equal the release number but is
+tied to it.
+
+The release number is available at *compile* time through the following
+macros defined in FT_FREETYPE_H:
+
+ - FREETYPE_MAJOR: major release number
+ - FREETYPE_MINOR: minor release number
+ - FREETYPE_PATCH: patch release number
+
+See below for a small autoconf fragment.
+
+The release number is also available at *runtime* through the
+`FT_Library_Version' API.
+
+
+2. History
+----------
+
+The following table gives, for all releases since 2.3.0, the
+corresponding libtool number, as well as the shared object number found
+on _most_ systems, but not all of them:
+
+
+ release libtool so

+
+3. Autoconf Code Fragment
+-------------------------
+
+Lars Clausen contributed the following autoconf fragment to detect which
+version of FreeType is installed on a system. This one tests for a
+version that is at least 2.0.9; you should change it to check against
+other release numbers.
+
+
+ AC_MSG_CHECKING([whether FreeType version is 2.0.9 or higher])
+ old_CPPFLAGS="$CPPFLAGS"
+ CPPFLAGS=`freetype-config --cflags`
+ AC_TRY_CPP([
+
+#include <ft2build.h>
+#include FT_FREETYPE_H
+#if (FREETYPE_MAJOR*1000 + FREETYPE_MINOR)*1000 + FREETYPE_PATCH < 2000009
+#error Freetype version too low.
+#endif
+ ],
+ [AC_MSG_RESULT(yes)
+ FREETYPE_LIBS=`freetype-config --libs`
+ AC_SUBST(FREETYPE_LIBS)
+ AC_DEFINE(HAVE_FREETYPE,1,[Define if you have the FreeType2 library])
+ CPPFLAGS="$old_CPPFLAGS"],
+ [AC_MSG_ERROR([Need FreeType library version 2.0.9 or higher])])
