+If you want to distribute panda sources, it is convenient to package

+in the makepanda directory.  You will need to give your version of

+BUILDING A LINUX RPM PACKAGE

+To build an RPM, first you need the tar-ball.  Once you have the
+tar-ball, the command to turn it into a binary RPM is as follows:
 
 	rpmbuild -tb panda3d-58.23.95.tar.gz
 
 Before you use rpmbuild, you need to set up an RPM workspace.  Doing
 so is beyond the scope of this document.

+BUILDING A WINDOWS INSTALLER
+
+Under Windows, makepanda can create an executable installer.  All you
+need to do is pass the --installer option to makepanda.  The makepanda
+option --lzma will cause the installer to be compressed with LZMA
+compression, which is better, but it takes a long time to do the
+compression.

+BUILDING A LINUX DEB PACKAGE

+you have to be using a Linux distribution that includes the deb
+utilities.
