mini­page-margin­par – Mini­pages with marginal notes

This pack­age al­lows \margin­par-com­mands in­side of mini­pages and other boxes. (It takes an­other ap­proach than margin­note by Markus Kohm: it saves all \margin­par-com­mands and type­sets them out­side (i.e., af­ter) the box.)
The pack­age de­fines an en­vi­ron­ment mini­page­with­margin­pars (to be used like mini­page)—and the in­ter­nal com­mands may be used by other pack­ages to de­fine sim­i­lar en­vi­ron­ments or com­mands.
