27     # A Perl script to return various information about a host machine
28     # by examining the output of some common Unix/Linux commands.
29     # This is a stopgap to act as a generic way of collecting the
30     # data. It is perhaps more reliable than the current Java host
31     # at doing this and it can obviously be used by a C++ program as
32     # well until the C++ host is ready to find the information out
33     # itself.
