Just one quick remark. The web page for the software says "Note, however, most computations and manipulations remained in a shared C++ library (libSA_lib.so), so the initial release was only for linux systems. Thanks to Fedor Andreev there is now a Windows version. (The longer range plan is to port the C++ code so the software is pure Java.)" So it looks like the core library will be a pure java program at some point though it is currently a C++ library -- this doesn't play well with Sage, at least not right now. > ---------- Forwarded message ---------- > From: Edward Crane <[EMAIL PROTECTED]> > Date: 12 Feb 2008 08:27 > Subject: Circle packing package > To: John Cremona <[EMAIL PROTECTED]> > > > Hello, John - you picked a working email address for me.
