=head1 NAME

share_usage_with_koha_community.pl - Share your library's usage with the Koha community

=head1 SYNOPSIS

share_usage_with_koha_community.pl [-h|--help] [-v|--verbose] [-f|--force] [-q|--quiet]

If the UsageStats system preference is set, you can launch this script to share your usage data
anonymously with the Koha community.

Collecting Koha usage statistics will help developers to know how Koha is used across the world.

This script will send the usage data for the bibliographic and authority records, checkouts, holds, orders,
and subscriptions.

Only the total number is retrieved. In no case will private data be shared!

In order to know which parts of Koha modules are used, this script will collect some system preference values.

If you want to tell us who you are, you can fill the UsageStatsLibraryName system preference with your library name, UsageStatsLibraryUrl, UsageStatsLibraryType and/or UsageStatsCountry, UsageStatsLibrariesInfo.

All these data will be analyzed on the http://hea.koha-community.org Koha community website.

IMPORTANT : please do NOT run the cron on the 1st, but on another day. The idea is to avoid all
Koha libraries sending their data at the same time ! So choose any day between 1 and 28 !
