#  In response to a user request I have put together this tiny package for    #
#  people to play with who want to start learning how to do page layout and   #
#  galleys with Lout.  It produces a very simple sequence of pages.  To       #
#  invoke the package, run "lout myfile > op" where myfile looks like this:   #
