# -- PUBLIC METHODS

#
# $wrapping->wrap( $storage, $ip );
#
# Wrap $ip in $storage according to this module wrapping algorithm. Note
# that $ip is already out of bounds, ie, it has been moved once by LBI.
# As a side effect, $ip will have its position changed.
#
# LBW implements a wrapping that dies. It's meant to be overridden by
# other wrapping classes.
