=head1 NAME
FS::h_cust_pkg - Historical record of customer package changes
=head1 SYNOPSIS
=head1 DESCRIPTION
An FS::h_cust_pkg object represents historical changes to packages.
FS::h_cust_pkg inherits from FS::h_Common and FS::cust_pkg.
=head1 CLASS METHODS
=over 4
=item search HASHREF
Like L<FS::cust_pkg::search>, but adapted for searching historical records.
Takes the additional parameter "date", which is the timestamp to perform
the search "as of" (i.e. search the most recent insert or replace_new record
for each pkgnum that is not later than that date).

$date =~ /^\d*$/ or die "invalid search date '$date'\n";

# this might be useful in the base cust_pkg search, but I haven't
# tested it there yet
