13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	71 AnaGram contains an LALR-1 parser generator which creates a

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	74 Backus-Naur form. AnaGram works in two steps. In the first step,
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	75 or analysis phase, it reads a <em>syntax
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	76 file</em> and compiles a number of tables describing the grammar. In
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	77 the second step, or build phase, it writes two output files: a
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	78 <em>parser file</em>, written in C or C++, and a header file.

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	99 Syntax files normally have the extension <tt>.syn</tt>. The rules for

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	109 The first step in writing a program is to write a grammar in
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	110 AnaGram notation which describes the input the program expects.<p>
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	111 The file containing the grammar, called the <em>syntax file</em>, should have
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	112 the extension <tt>.syn</tt>. You could also make up a few sample input

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	121 time. There are, however, many aids available to help you with
