SaVi

Today I released SaVi 1.4.4.

SaVi is software for simulation and visualization of satellite orbits, especially satellite constellations such as Iridium, Globalstar and O3b.

This point release builds on Tcl/Tk 8.6b1, updates script simulating O3b based on latest information, adds simulations of Japanese NeLS rosette and COMMstellation constellations, allows selection between existing J2 and classical J0 orbital models with -orbit-model flag, provides keyboard menu shortcuts (except on buggy Mac Tk), warns against deletion of help textfiles, supports building with just 'make' on x86_64 linux systems, adds notes on packaging and release processes.

All minor stuff, really. Although I'll continue to add to SaVi as and when it's needed, I can't yet see any reason for another release before 2012...
