-This document describes how to build SimGear using the supplied workspace and
-project files.  
-
-Unpack the SimGear source file into your work directory.  This creates a new
-subdirectory called SimGear-X.Y.Z.  Rename this to SimGear.  Before we can
-build SimGear you must unpack and build the third party libraries metakit and
-zlib.  Sources for these are included in the SimGear/src-libs directory.
-Unpack these into the top level SimGear directory.  At this point your
-directory structure should look something like this:
-
-<work_dir>/
-  SimGear/
-    metakit-x.y.z/
-    simgear/
-    src-libs/
-    zlib-x.y.z/
-
-Now open the SimGear workspace.  This workspace file contains projects for
-building metakit(mklib), SimGear and zlib.  Select each project as the active
-project and build all.  Order is unimportant since there are no dependencies
-between the projects.
-
-The workspace and project files are generated by a perl script with extra
-input from the am2dsp.cfg file.
