=head1 NAME

pseudonymize_statistics - This script pseudonymizes statistics before a given date, or now if no date passed.

NOTE: If patrons or items have been deleted their fields cannot be saved, additionally the fields will use current

values as the ones from when the transaction occurred are not available.

=head1 SYNOPSIS

pseudonymize_statistics.pl [-h|--help] [-v|--verbose] [-b|--before=DATE]

=head1 OPTIONS

=over

=item B<-h|--help>

Print a brief help message

=item B<-v|--verbose>

Verbose mode.

=item B<-b|--before=DATE>

This option allows for specifying a date to pseudonmyize before. Useful if you have enabled pseudonymization and want to pseudonymize transactions before that date. If not passed all statistics before current time will be pseudonymized.
