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

# by examining the output of some common Unix/Linux commands. |

# 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. |
