Bugzilla::UserAgent - UserAgent utilities for Bugzilla
=head1 SYNOPSIS
use Bugzilla::UserAgent;
printf "platform: %s op-sys: %s\n", detect_platform(), detect_op_sys();
=head1 DESCRIPTION
The functions exported by this module all return information derived from the
remote client's user agent.
=head1 FUNCTIONS
=over 4
=item C<detect_platform>
This function attempts to detect the remote client's platform from the
presented user-agent. If a suitable value on the I<platform> field is found,
that field value will be returned. If no suitable value is detected,
C<detect_platform> returns I<Other>.
=item C<detect_op_sys>
This function attempts to detect the remote client's operating system from the

field value will be returned. If no suitable value is detected,
C<detect_op_sys> returns I<Other>.
