@code{:eval} was a new feature in GNU Emacs version 21. It says to
evaluate the following form and use the result as a string to display.
In this case, the expression displays the first component of the full
system name. The end of the first component is a @samp{.} (`period'),
so I use the @code{string-match} function to tell me the length of the
first component. The substring from the zeroth character to that
length is the name of the machine.

Local variables can only be accessed

them in an argument list (and within expressions called by them).
