# 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. |
