                      2: This is a test of the refer program.
                      3: Because the bibliography supplied by Bell Labs
                      4: contains nothing but programming references, 
                      5: that will be the subject here.
                      6: .PP
                      7: For serious programmers, there are several
                      8: indispensable reference works.
                      9: The book describing the C programming language
                     10: is an excellent starting place for those

                     16: It is rich with examples of programs that work,
                     17: probably the most valuable resource a programming book can provide.
                     18: .PP
                     19: When learning the Unix system,
                     20: it will be necessary to have a reference guide
                     21: such as the Programmer's Manual.
                     22: Section 1 is useful for everyone,
                     23: but only programmers need sections 2 through 8.

                     30: .PP
                     31: One of the strong suits of the Unix system is the ability
                     32: to build parsers and compilers for new languages.
                     33: Several tools are provided to this end,
                     34: most notably \fIlex\fP and \fIyacc\fP.
                     35: For an introduction to the theory involved,
                     36: see the book by Aho and Ullman on LALR parsing.
