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