% \spine{text} makes a boxed label for the spine of a 3 ring binder
% This is printed in \Landscape mode, 24pt type, and with a ruled box
% around it.  The box will be at least 15cm long, but will extend
% if the text requires more space.  Instructions for installing the
% label in the spine of a binder are printed, but if more than one
% label is created the instructions are only printed once.

     How to install the spine label on a binder:

     \item{1.}
     Cut out the label around the outside of the 
     bounding ruled box.  Leave extra paper
     (about 1.5cm or so) on the RIGHT side.

     \item{2.}
     Obtain a long thin plastic ruler or similar object which can 
     slide down the pocket on the binder spine.

     \item{3.}
     Put the label along the ruler, face up, and fold the extra tab 
     of paper on the right of the label over the end of the ruler.

     \item{4.}
     Slide the ruler, with the label on it, down the spine of the 
     binder.  When the label is in place remove the ruler.  The label 
     will remain.
