The package draws Discourse Representation Structures (DRSs). It can draw embedded DRSs, if-then conditions and quantificational “duplex conditions” (with a properly scaled connecting diamond). Formatting parameters allow the user to control the appearance and placement of DRSs, and of DRS variables and conditions.

The package is based on DRS macros in the covington package.
