+ .................................
+
+ Note that there is a chicken-and-egg problem currently since the
+ HarfBuzz library (used by the auto-hinter to improve support of
+ OpenType fonts) depends on FreeType, which can be solved as
+ follows in case HarfBuzz is not yet installed on your system.
+
+ 1. Call FreeType's configure script with option
+ `--without-harfbuzz', then compile and install FreeType.
+
+ 2. Compile and install HarfBuzz.
+
+ 3. Call FreeType's configure script without option
+ `--without-harfbuzz', then compile and install FreeType again.
