[rtl] rtlinux-2.2 and rtlinux-2.2a

[Bruce L Gotwols <gotwols@clutter.jhuapl.edu>]

Hello,
	I am upgrading our airborne system that uses RTLinux V1
to version 2.  A note on the FSM web ftp site says that RTLinux 2.2 is the
latest stable version (we don't want an unstable version on the
airplane!). However, I find both rtlinux-2.2 and rtlinux-2.2a on the ftp
site.  Both have the same date and the release notes mention only the a
version.  Can someone tell me the difference between these two versions?
	Incidentally, the airborne system is an altimeter using a new
technique known as Delay Doppler processing.  We flew it in Greenland in
June and it worked perfectly.  RTLinux was used on two PC's communicationg
via TCP/IP and a third computer provided Quick Look and data storage.
RTLinux V1 worked beautifully, I hope V 2.2 will do as well.  This project
is described at fermi.jhuapl.edu/d2p, but alas I have not put up the web
pages relating to Linux yet on the project page.

	Thanks, Bruce
