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