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.
