+perfectcut.sty --- Nested delimiters that consistently grow regardless
+of the contents.
This package defines the command \perfectcut#1#2 which displays a
-bracket <#1||#2>. Its effect is to determine the size of the bracket
-depending on the number of nested \perfectcut (regardless of the
-contents). It is intended for use:
-- In proof theory, for term notations of sequent calculus,
-- In computer science, for the modeling of abstract machines.
+bracket <#1||#2>. Various delimiters are similarly defined. The effect
+of these commands is to let the delimiters grow according to the number
+of nested \perfectcommands (regardless of the size of the contents).
-This package also offers a reimplementation of \big, \bigg, etc. into
-arbitrary-size variants.
+The package is originally intended for solving a notational issue
+regarding the representation of abstract-machine-like calculi in proof
+theory and computer science. For general use, the package also defines
+commands for defining custom delimiters that behave in the same way.

+This package also offers a sound reimplementation of \big, \bigg, etc.
Release notes:
+ 2.0 11/14: * The package now offers general-purpose commands for
+ defining arbitrary nested delimiters that consistently
+ grow regardless of the contents (\perfectunary and
+ \perfectbinary)
+ * Added the behaviours CurrentHeight and
+ CurrentHeightPlusOne alongside the existing behaviour
+ IncreaseHeight.
+ * Added the stock commands \perfectcase, \perfectparens,
+ and \perfectbrackets intended for use in the context
+ of abstract-machine-like calculi.
+ 1.9b 05/14: added the option fixxits to fix vertical alignment with the
+ XITS math font.
