la­belfig – La­bel LaTeX 2.09 fig­ures in­cluded in doc­u­ments

The user spec­i­fies a ta­ble of la­bels (in a group \SetLa­bels ... \endSetLa­bels), and then in­cludes the graphic and places the la­bels at the same time us­ing the com­mand \Af­fixLa­bels.
The pack­age can draw a grid over your fig­ure, to ease es­ti­ma­tion of the la­bels' re­quired lo­ca­tion.
