+     "LaTeX, by default, restricts the sizes at which you can use its default
+computer modern fonts, to a fixed set of discrete sizes (effectively, a set
+specified by Knuth).  The @code{type1cm} package removes this restriction;
+this is particularly useful when using scalable versions of the CM
+fonts (Bakoma, or the versions from BSR/Y&Y, or True Type versions from Kinch,
+PCTeX, etc.).  In fact, since modern distributions will automatically generate
+any bitmap font you might need, @code{type1cm} has wider application than just
+those using scaleable versions of the fonts.  Note that the LaTeX distribution
+now contains a package @code{fix-cm},f which performs the task of
+@code{type1cm}, as well as doing the same job for T1- and TS1-encoded
+@code{ec} fonts.")
