1.1       root        1: #print
                      2: Bars are not the only characters you can put 
                      3: around an equation.
                      4: If you say
                      5:   left (  thing  right )
                      6: you will get large parentheses around "thing".
                      7: You can also use [ and ] for large square brackets
                      8: and { and } for large braces.
                      9: 
                     10: The main problem is that on your terminal there is
                     11: no good way for neqn to draw large braces
                     12: or brackets or parens.  So neqn replaces all of these
                     13: with bars.
                     14: Use the right character anyway, though - things do
                     15: work properly on the typesetter.  And who knows, some day
                     16: neqn may get improved as well.
                     17: 
                     18: With the current version of neqn, does the input
                     19:   left { a over b right }
                     20: produce the same output as
                     21:   left [ a over b right ]
                     22: Answer yes or no.
