+     "This package defines the command @code{\\perfectcut#1#2} which displays
+a bracket @samp{<#1||#2>}.  Various other delimiters are similarly
+defined (parentheses, square brackets ...).  The effect of these commands is
+to let the delimiters grow according to the number of nested
+@code{\\perfectcommands} (regardless of the size of the contents).
+
+The package was originally intended for solving a notational issue for
+direct-style continuation calculi in proof theory.  For general use, the
+package also defines commands for defining other sorts of delimiters which
+will behave in the same way.  The package also offers a robust
+reimplementation of @code{\\big}, @code{\\bigg}, etc.")
