+look worse with \embrac\ than without.
 
 The following example demonstrates one point why you have to be very careful
 when using \embrac.  Certain parenthesis-letter combinations might need
 adjustments of the kerning:
-\begin{beispiel}
- \emph{This is (just) emphasized text.} \\
- \emph{This is (\kern.1em just) emphasized text.}
-\end{beispiel}
+\begin{example}
+  \emph{This is (just) emphasized text.} \par
+  \emph{This is (\kern.1em just) emphasized text.}
+\end{example}
 This of course strongly depends on the font you've chosen.  Kerning is a very
 important aspect when using this package and you shouldn't use it without
 giving it a certain amount of attention.  See the next section for more

 \section{Adding More Brackets \&\ Adjusting the Kerning}
-\secidx{Adding More Brackets}\secidx{Adjusting the Kerning} If you want you
-can change the behaviour of \embrac.  Maybe it should only affect squared
-brackets?  Or curly braces, too?  This can be done with the following
-commands.  They all work locally which means if used inside a group outside of
-it everything stays what it was.
-\begin{beschreibung}
- \Befehl{AddEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
- \Befehl{ChangeEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
- \Befehl{RenewEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
- \Befehl{DeleteEmph}{<o>}\ma{<c>}
-\end{beschreibung}
-Here \code{<o>} means \emph{opening bracket} and \code{<c>} means
-\emph{closing bracket}.  The kerning arguments are all four optional and
-require -- if given -- to be a length.  If they're not given \cmd{AddEmph} and
-\cmd{RenewEmph} insert \code{0pt} and \cmd{ChangeEmph} uses the value stored
-by \cmd{AddEmph} or \cmd{RenewEmph} before.

+affect squared brackets?  Or curly braces, too?  This can be done with the

+\begin{commands}
+  \command{AddEmph}[\marg{o}\Oarg{\meta{io-kern},\meta{oo-kern}}%
+    \marg{c}\Oarg{\meta{ic-kern},\meta{oc-kern}}]
+    Add a pair of brackets to be left upright in italic text.
+  \command{ChangeEmph}[\marg{o}\Oarg{\meta{io-kern},\meta{oo-kern}}%
+    \marg{c}\Oarg{\meta{ic-kern},\meta{oc-kern}}]
+    Change the kerning values for a given pair of brackets.
+  \command{RenewEmph}[\marg{o}\Oarg{\meta{io-kern},\meta{oo-kern}}%
+    \marg{c}\Oarg{\meta{ic-kern},\meta{oc-kern}}]
+    Renew the kerning values for a given pair of brackets.  See below for the
+    difference to \cs{ChangeEmph}.
+  \command{DeleteEmph}[\marg{o}\marg{c}]
+    Remove a pair of brackets from treatment.
+\end{commands}
+In the above descriptions \meta{o} means \emph{opening bracket} and \meta{c}
+means \emph{closing bracket}.  The kerning arguments are all four optional and
+require -- if given -- to be a length.  If they're not given \cs{AddEmph} and
+\cs{RenewEmph} insert \code{0pt} and \cs{ChangeEmph} uses the value stored by
+\cs{AddEmph} or \cs{RenewEmph} before.
 
 \sinceversion{0.4}To each of these commands there are two variants that are
 only semantically different\footnote{They're also using different lists
   internally but you shouldn't concern yourself with this.}.  They are all
-called \cmd*{<base>OpEmph} or \cmd*{<base>ClEmph} where \code{<base>} is
+called \cs*{\meta{base}OpEmph} or \cs*{\meta{base}ClEmph} where \meta{base} is
 either \code{Add}, \code{Change}, \code{Renew} or \code{Delete}.  Their
 arguments are all the same: the half of what the main commands have for either
 modifying the opening or the closing symbols.
-\begin{beschreibung}
- \Befehl{AddOpEmph}{<o>}\oa{<io-kern>,<oo-kern>}
- \Befehl{AddClEmph}{<c>}\oa{<ic-kern>,<oc-kern>}
-\end{beschreibung}
+\begin{commands}
+  \command{AddOpEmph}[\marg{o}\Oarg{\meta{io-kern},\meta{oo-kern}}]
+    An an opening bracket to the treatment.
+  \command{AddClEmph}[\marg{c}\Oarg{\meta{ic-kern},\meta{oc-kern}}]
+    An a closing bracket to the treatment.
+\end{commands}
 They allow you to add single symbols to \embrac's mechanism instead of adding
 pairs.
 
-In all these commands the optional argument \code{<io-kern>} is inserted after
-the opening bracket (inner opening), \code{<oo-kern>} is inserted before it
-(outer opening). \code{<ic-kern>} is inserted before the closing bracket
-(inner closing), \code{<oc-kern>} after it (outer closing).
+In all these commands the optional argument \meta{io-kern} is inserted after
+the opening bracket (inner opening), \meta{oo-kern} is inserted before it
+(outer opening). \meta{ic-kern} is inserted before the closing bracket (inner
+closing), \meta{oc-kern} after it (outer closing).
 
-\embrac initially makes these definitions:
-\begin{beispiel}[code only]
- % add some defaults:
- \AddEmph{[}{]}[.04em,-.12em]
- \AddEmph{(}[-.04em]{)}[,-.15em]
-\end{beispiel}
+\embrac\ initially makes these definitions:
+\begin{sourcecode}
+  % add some defaults:
+  \AddEmph{[}{]}[.04em,-.12em]
+  \AddEmph{(}[-.04em]{)}[,-.15em]
+\end{sourcecode}
 
 This document however uses ``Linux Libertine
 O''\footnote{\url{http://www.linuxlibertine.org/}} both for the roman and the
 italic font and redefines them in this way (still not sure these are the best
 values):
-\begin{beispiel}[code only]
- \RenewEmph{[}[-0.045em,.02em]{]}[.055em,-.09em]
- \ChangeEmph{(}[-.01em,.04em]{)}[.04em,-.05em]
-\end{beispiel}
+\begin{sourcecode}
+  \RenewEmph{[}[-0.045em,.02em]{]}[.055em,-.09em]
+  \ChangeEmph{(}[-.01em,.04em]{)}[.04em,-.05em]
+\end{sourcecode}
 
 You can change them as you wish, but be careful with the kerning! What's too
 less for one letter might be too much for others:
-\begin{beispiel}
- \ChangeEmph{(}[.1em]{)}[.1em]
- \emph{This is (just) emphasized text.} \\ % looks ok
- \emph{This is emphasized text (as you can see).} % looks bad
-\end{beispiel}
+\begin{example}
+  \ChangeEmph{(}[.1em]{)}[.1em]
+  \emph{This is (just) emphasized text.} \par % looks OK, kind of
+  \emph{This is emphasized text (as you can see).} % looks bad
+\end{example}
 
 To see why it is important to pay attention to the kerning values let's look
 at how \embrac's features look without kerning (\ie, \code{0pt} for each
 value), with the default settings and with the settings for this document:

 \end{center}
 
 Deleting a pair removes it completely from \embrac's mechanism.  All
 information about the pair and its kerning values will be lost.  So if you
 want the effects to be temporary use grouping.
-\begin{beispiel}
- \DeleteEmph{[}{]}
- \emph{This is emphasized [sic] text.} \\
- \emph{This is emphasized text (as you can see).}
-\end{beispiel}
+\begin{example}
+  \DeleteEmph{[}{]}
+  \emph{This is emphasized [sic] text.} \par
+  \emph{This is emphasized text (as you can see).}
+\end{example}
 
 By the way: this packages provides a simple file
 \code{embrac\_kerning\_test.tex} for testing kerning values.  You should find
-it in the same directory as this documentation.  \secidx*{Adding More
