 \subsection else-description Description
-<tt>if</tt> will execute the command CONDITION.  If the condition's exit
-status is 0, the commands COMMANDS_TRUE will execute.  If it is not 0 and
-<tt>else</tt> is given, COMMANDS_FALSE will be executed.  Hint: use
-<a href="#begin"><tt>begin; ...; end</tt></a> for complex conditions.
+<tt>if</tt> will execute the command \c CONDITION. If the condition's exit
+status is 0, the commands \c COMMANDS_TRUE will execute. If it is not 0 and
+<tt>else</tt> is given, \c COMMANDS_FALSE will be executed.
 
 \subsection else-example Example
 
-The command <tt>if test -f foo.txt; echo foo.txt exists; else; echo foo.txt does not exist; end</tt>
-will print <tt>foo.txt exists</tt> if the file foo.txt
-exists and is a regular file, otherwise it will print
-<tt>foo.txt does not exist</tt>.
+The following code tests whether a file \c foo.txt exists as a regular file.
+
+<pre>
+if test -f foo.txt
+    echo foo.txt exists
+else
+    echo foo.txt does not exist
+end
+</pre>
