+A simple example (with alltt) showing steps with verbatim text.
+Multiple lines in one step is only supported by alltt (and only for the
+standard step command, not bstep).

+
+An easy example (with listings) for including small parts of code in each step.
+If you want to include code line by line look at the next example. Notice that in this
+example you really don't need to use the fragilesteps environment, because
+there are no verbatim code - the next example however...

+
+A (fancy) example using the fancyvrb interface of the listings package.
+The re(b)step command is used to make some lines of code appear at the same time.
+(You can not include multiple lines in each (b)step command.)
