cat <<DISCLAIMER
This script collects some basic information regarding the system it's run on,
specifically it does the following:

1.  Counts the number of cores on your system
2.  Collects the vendor_id, cpu family, model, model name and stepping values of cpu 0 in /proc/cpuinfo.
3.  Determines the MAC of the lower PCI ID NIC in your system.
4.  Runs benchg729 a few times and extracts the timing values from it.
5.  Determines the arch as per "uname -m".
6.  The version of benchg729 that you have installed (which also contains the codec version).

This is the only information this script gathers.  It submits this data to
g729.uls.co.za, you can obtain some aggregated statistical data from this site
(it's public).  If you do not agree that your data be added into this data,
please terminate this script now.

This script will submit the run times for all codecs that the bench tool tests,
this is to allow us to with sufficient information discard outlier data.

Please attempt to run this script when the rest of your system is idle in order
to provide the most accurate possible results.
