# A Perl script to return various information about a host machine |
| 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. |
