Bison News
----------
Change in version 1.25:
* Errors in the input grammar are not fatal; Bison keeps reading
the grammar file, and reports all the errors found in it.
* Tokens can now be specified as multiple-character strings: for
example, you could use "<=" for a token which looks like <=, instead
of chosing a name like LESSEQ.
* The %token_table declaration says to write a table of tokens (names
and numbers) into the parser file. The yylex function can use this
table to recognize multiple-character string tokens, or for other
purposes.
* The %no_lines declaration says not to generate any #line preprocessor
directives in the parser file.
* The %raw declaration says to use internal Bison token numbers, not
Yacc-compatible token numbers, when token names are defined as macros.
* The --no-parser option produces the parser tables without including
the parser engine; a project can now use its own parser engine.
The actions go into a separate file called NAME.act, in the form of
a switch statement body.
