=head1 NAME

if - C<use> a Perl module if a condition holds

=head1 SYNOPSIS

use if CONDITION, MODULE => ARGUMENTS;

=head1 DESCRIPTION

The construct

use if CONDITION, MODULE => ARGUMENTS;

has no effect unless C<CONDITION> is true.  In this case the effect is
the same as of

use MODULE ARGUMENTS;

Above C<< => >> provides necessary quoting of C<MODULE>.  If not used (e.g.,
no ARGUMENTS to give), you'd better quote C<MODULE> yourselves.

=head1 BUGS

The current implementation does not allow specification of the
required version of the module.
