+     "In every quantum field theory course, there will be a chapter about
+Wick's theorem and how it can be used to convert a very large product of many
+creation and annihilation operators into something more tractable and normal
+ordered.  The contractions are denoted with a square bracket over the
+operators which are being contracted, which used to be rather annoying to
+typeset in LaTeX as the only other package available was simplewick, which is
+rather unwieldy.  This package provides a simpler syntax for Wick
+contractions.")
