\section{Description}

\Prog{wmiiloop} is an awk and sh script which preprocesses \Cmd{sh}{1} syntax
to simplify writing a wmii event loop.

\Prog{wmiiloop} associates lines begining with \emph{Event}, \emph{Action}, or
\emph{Key} (henceforth known as \textbf{\$keyword}), followed by arbitrary
text (henceforth known as \textbf{\$args}), with functions which call any
indented lines which follow.  In the function names, all non-alphanumeric
characters in \textbf{\$args} are replaced with underscores (\_). The
functions are named \textbf{\$keyword}'_'\textbf{\$args}.

Any variables in the unintented lines are interpolated by the shell.

Additionally, each declaration's \textbf{\$args} are assigned to a variable
named \textbf{\$keyword}'s'. In this case, no transliteration occurs. For
instance, the following declaration:

\begin{verbatim}
Key $MODKEY-j
	echo Got $@
\end{verbatim}
yields (assuming \emph{\$MODKEY} is set to \emph{Mod1}):

\begin{verbatim}
Keys=" $Keys Mod1-j"
Mod1_j() {
	echo Got $@
}
\end{verbatim}
