/*
This is just a little proggie to scan the www server for their
server type and version.
I cannot and will not be held responsible nor legally bound for the
malicious activities of individuals who come into possession of this
[03.10.99] - v1.02 some lame segmentation faults fixed :\
[20.09.99] - v1.01 added the option for mass scan
