+     "The package provides simple commands to allow authors (especially scholars in
+the humanities) to write with a focus on content rather than presentation.
+The commands are inspired by the XML elements of the Text Encoding Initiative.
+Commands like @code{\\term} and @code{\\foreign} are aliases for
+@code{\\emph}.  @code{\\quoted} and @code{\\soCalled} are aliases for quoting
+commands.  These commands could be easily redefined for different formats.
+The package also provides a @code{footnote} environment so that long footnotes
+can be more cleanly separated from the main text.  Eventually, the package
+also includes some macros for musical symbols and other basic notations for
+musical analysis.")
