+(4) The above will generate both a src and binary (probably i386) rpm
+    You can always generate a binary rpm from a source rpm using e.g.
+
+        rpmbuild --rebuild nexus-2.0.0-1.src.rpm
+
+    While re-building files will be copied to a
+    temporary installation directory structure under /tmp/nexus-2.0.0
+    You may change this location using the  --buildroot  option, but
+    be very careful as the "build root" may ultimately get removed by rpm.
+    In particular, DO NOT give "/" as the build root.
+
+    If you want the final files installed in a different directory to
+    the defaults (/usr/local/{bin,lib,nexus}), get/build the binary rpm 
+    and then use the  rpm --prefix  installation option e.g.
+
+        rpm -ivh --prefix /opt nexus-2.0.0-1.i386.rpm
+
+    will install the files to /opt/{bin,lib,nexus}
