+Building a SimGear RPM package for Red Hat
+
+Please see the "package/openSUSE" directory for an
+example how to build a SimGear RPM package with
+shared SimGear libraries.
+
+You may need to adapt the names (exact spelling) of some
+of the package dependencies in the openSUSE RPM spec,
+since these may slightly differ for Red Hat.
+
+(If you have a working and tested Red Hat RPM spec,

+Building a SimGear RPM package for openSUSE
+
+(Last tested with openSUSE 11.4+12.1)
+
+This directory contains the files which, along with
+the source code tar files, can be used to build
+an RPM package targeted at an openSUSE Linux system.
+
+To build SimGear from source do the following:
+
+1. obtain simgear-2.8.0.tar.bz2 (adapt version if
+    necessary) and copy it into ~/rpmbuild/SOURCES
+
+2. look in the BuildRequires section of SimGear.spec
+   and check that all the packages referred to are
+   installed (note, some of these packages may be part
+   of openSUSE's "games" repository).
+
+3. run 'rpmbuild -ba simgear.spec' and find the RPM
+   build result in ~/rpmbuild/RPMS
+
+That's all!
