+     "LaTeX's default style of typesetting mathematics does not comply with
+the International Standards ISO 31-0:1992 to ISO 31-13:1992 which require that
+uppercase Greek letters always be typset upright, as opposed to italic (even
+though they usually represent variables) and allow for typsetting of variables
+in a boldface italic style (even though the required fonts are available).
+This package ensures that uppercase Greek be typeset in italic style, that
+upright @samp{$\\Delta$} and @samp{$\\Omega$} symbols are available through
+the commands @code{\\upDelta} and @code{\\upOmega}; and provides a new math
+alphabet @code{\\mathbold} for boldface italic letters, including Greek.")
