BNF Module README


INTRODUCTION


  The t-bnf module implements a way to easily write BNF grammars in CONTEXT.
  Let's look at an example BNF grammar in a document:

  \starttext

  Here's a \BNF\ grammar.  Enjoy. 

  \placebnfgrammar
    [here]
    [bnf:test]
    {A test of the \BNF\ module}
    {\startbnfgrammar[]
      <S>: a<S>b
      <S>: $\epsilon$
    \stopbnfgrammar}

  Which will match the language $L = \{\,a^nb^n \mid n \geq 0\,\}$.

  \stoptext

  You may try to generate module documenation embedded in t-bnf.tex with texexec
  as well:

  % texexec --interface=en --module --pdf t-bnf.tex

  If you have any issues with creating the documentation this may be a result
  of lacking the proper language format.  You can look up the proper
  information for generating these formats in minstall.pdf at PRAGMA-ADEs site
  (http://www.pragma-ade.com/).

  Enjoy!
