typo
This definition means that we can ask for the meaning of a unit using <cmd>unitmeaning</cmd> and get a list of used units by saying <cmd>placelistofunits</cmd>.
We have to use the command <cmd>unitmeaning</cmd> instead of <cmd>meaning</cmd>, simply because the latter is a TeX primitive we don't want to looselose. We use the label text mechanism for translations.
