Version 0.5.3 on the wire

i.e. on <ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/>. There has been a bug in the last version where .normal() was returning wrong results for certain rational functions like 1/(5-4*a)*(-5-2*a-(3+2*a)*(2-5*a)/(-2+a)) which is now fixed. Also, this version features an improved and more flexible scheme for registering functions which makes extensions easier and also allows writing remembering functions in a clean way. See <http://www.ginac.de/reference/class_remember_table.html>. GiNaC-cint is making slow progress---we have it running with the current cint 5.14.31 now. Sex and drugs and Unix -rbk. -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
