#25.06.2005 - PleuR     : int_to_byte, ratio-fixer, fixed line 1 (is connected to online ?)
#16.12.2005 - stefanero : some kad cleanups
#12.12.2005 - fulgas	; made kad work with xas
#06.05.2005 - niet      : file handle change
#12.10.2004 - bisley    : added session/total ratios
#16.06.2004 - niet      : added support for memory usage and binary name
#05.05.2004 - Jacobo221 : fixed typos, sig 2 support, new outputs, crash detect 
#29.04.2004 - niet      : renamed astats to xas (X-Chat Amule statistics)
#22.04.2004 - citroklar : added smp support
#      2004 - bootstrap : some hints on file opening
#      2004 - niet      : used some of cheetah.pl script and so astats was born
