+SUMMARY="A MusiXTEX extension library that enables transformations"
+DESCRIPTION="musixtnt.tex provides a macro \\TransformNotes that enables transformations of the \
+effect of notes commands such as \\notes. In general, the effect of \
+\\TransformNotes{input}{output} is that notes commands in the source will expect their arguments \
+to match the input pattern, but the notes will be typeset according to the output pattern. An \
+example is extracting single-instrument parts from a multi-instrument score.
+fixmsxpart corrects note spacing in a single-part MusiXTEX source (possibly derived from a \
+multi-instrument score and as a result having irregular note spacing).
+msxlint detects incorrectly formatted notes lines in a MusiXTEX source file. This should be used \
+before using \\TransformNotes."
