+    (description
+     "The Helmholtz-Ellis JI Pitch Notation (HEJI), devised in the early 2000s
+by Marc Sabat and Wolfgang von Schweinitz, explicitly notates the raising and
+lowering of the untempered diatonic Pythagorean notes by specific microtonal
+ratios defined for each prime.  It provides visually distinctive logos
+distinguishing families of justly tuned intervals that relate to the harmonic
+series.  These take the form of strings of additional accidental symbols based
+on historical precedents, extending the traditional sharps and flats.  Since
+its 2020 update, HEJI version 2 (HEJI2) provides unique microtonal symbols
+through the 47-limit.  This package is a simple LaTeX implementation of HEJI2
+that allows for in-line typesetting of microtonal accidentals for use within
+theoretical texts, program notes, symbol legends, etc.  Documents must be
+compiled using XeLaTeX.")
