+You need to have the GPC library installed on your system to build
+some of the scenery generation tools, otherwise you won't be able to
+create scenery.
+
+You can get the library from:
+
+    http://www.cs.man.ac.uk/aig/staff/alan/software/
+
+Unfortunately, because of some of the wording in the GPC licensing
+terms we are unable to include the GPC library with the Flight Gear
+distribution.
+
+This library comes as a single source file and header with no build
+directions.  So, here are some directions contributed by Riley Rainey
+<riley.rainey@websimulations.com>:
+
+
+1. Download the GPC library source code from URL:
+
+	http://www.cs.man.ac.uk/aig/staff/alan/software
+
+2. Unpack it; the current version seems to be 2.22:
+
+	$ zcat gpc222.tar.Z | tar xvf -
+
+3. Copy in the Makefile attached to this message:
+
+	$ cp Makefile ./gpc222
+
+4. Check install paths.  Edit the Makefile and make sure the install
+   paths are satisfactory.  Also make sure that all the make commands
+   have leading tabs (i.e. that the tabs aren't expanded out into 8
+   spaces) otherwise the make will fail.
+
+5. Build and install it:
+
+	$ cd ./gpc222
+	$ make
+	$ su
+	Password:
+        # make install
+
+
