|
=head1 DESCRIPTION
|
|
|
|
This script collects usage information of the local system and sends it to the
|
|
ZoneMinder development team. This data will be used to determine things like
|
|
who and where our customers are, how big their systems are, the underlying
|
|
hardware and operating system, etc. This is being done for the sole purpoase of
|
|
creating a better product for our target audience. This script is intended to
|
|
be completely transparent to the end user, and can be disabled from the web
|
|
console under Options.
