        !             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

        !             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,

        !            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.

        !            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.
