-It is usually wise to do your formatting with
-the "-ms" macro package developed by Mike Lesk, since
-it does a lot of dirty work for you without any effort
-on your part.
-One of the things "-ms" does is to arrange that equations
-are "displayed" - that is, that they are neatly centered
-and set off from the surrounding text.
-Most of the "-ms" package is described in another script
-called "macros", which you may have already learned.
-For now, we need only know this much: to use "-ms"
-with neqn, add "-ms" to your command line, right after
-the word "nroff", like this
-
- neqn files... | nroff -ms -Txxx
-
-Notice where the "-ms" goes.
-
-In this directory is a file called "Example".
-To prove that you can type the "-ms" in the right place,
-print "Example" with "-ms", then type "ready".
-#once #create Example
-.PP
-This is a tiny little text
-that includes one equation
-or at least it will when you find this line:
-.EQ
-x sub i = y sub i
-.EN
-and convert it into an equation.
-(Naturally I changed it.)
