+     "The @code{\\maybebm} and @code{\\maybeit} macros can be used in maths
+expressions to make the arguments typeset as bold or italic respectively if
+the surrounding context is appropriate.  They are useful for writing user
+macros for use in general contexts.  @code{\\maybebm} is especially
+appropriate when section titles contain math expressions, since the title will
+appear bold but the header and table of contents usually replicate the title
+in normal width.  @code{\\maybeit} performs a similar role to @code{\\mathrm}
+but the maths expression will be italicised if the surrounding text is.
+@code{\\maybeitsubscript} is provided to shift subscripts to the left if the
+expression is italicised.")
