-\subsection{Why a \texttt{complexity} package?}
-
-A better question is why not?  Complexity theory is a more recent,
-though mature area of Theoretical Computer Science.  Each researcher
-seems to have his or her own preferences as to how to typeset
-Complexity Classes and has built up their own personal \LaTeX\
-commands file. This can be frustrating, to say the least, when it
-comes to collaborations or when one has to go through an entire
-series of files changing commands for compatibility or to get
-exactly the look they want (or what may be required).  I find it
-amazing that a package hasn't been written \emph{already}!  (Maybe
-there has been, but I've not found it).
-
-I thought the best solution would be to develop a single \LaTeX\
-package to handle all of this for us.

-\section{Installation}
-
-You should place the |complexity| directory and its files
-(|complexity.sty| and |mycomplexity.sty| as well the documentation
-files if you like) in a place that your \TeX\ distribution will be
-able to find them.
-
-If you use MiK\TeX\ then you should place it in your |localtexmf|
-directory, making sure to refresh your \TeX\ tree (MiK\TeX\ options
-wizard $\rightarrow$ General $\rightarrow$ File Names Database,
-Refresh Now).
-
-In a unix \TeX\ distribution, you may find it useful to use a local
-\LaTeX\ path (i.e. creating a directory
-|/usr/local/username/mylatexfolder/| and tell your \TeX\
-distribution where to find it.  Depending on your distribution, you

-The |complexity| package defines three different font entities: a

 A special option is the |small| option and pertains only to how
 complexity classes (|classfont|) are typeset.  Since classes are
-typeset in uppercase letters, they tend to be more dominant.  This
-is not so important for classes such as $\P$ and $\NP$, but if you
-are referencing classes such as $\PSPACE$ or $\DTIME$ it can
+typeset in uppercase letters, they tend to be more dominant.  If
+you frequently typeset classes such as $\PSPACE$ or $\DTIME$ it can
 interrupt the normal flow of text layouts. One solution to this is
 to typeset classes 1pt smaller than the surrounding text.  This is
 the approach taken in some texts (most notably, Papadimitriou's book
-\emph{Computational Complexity}, 1994) and it works quite well.  To
-illustrate, consider the following:
-\begin{quote}
-There are deterministic classes such as $\PSPACE \hbox{\small

-\hbox{\small \NP}$\kern-.35em, and functional classes such as $\GapP
