NAME

       Polygen	- Polygen is a powerful gadget for creating spontaneous sentences according to a grammar definition, that is following custom syn-
       tactical and lexical rules.

SYNOPSIS

       polygen [options] sources

DESCRIPTION

       Polygen is a tool for creating incidental sentences according to a grammar definition, that is following  custom  syntactical  and  lexical
       rules.

       Formally,  it  is  an interpreter of a language itself designed to define languages, where to interpret means executing a source program in
       real time and eventually outputting its result.

       Here a source program is a grammar definition, the execution consists in the exploration of such grammar by selecting a random path and the
       result is the sentence built on the way.

       Though  PolyGen	is  quite a seriuos piece of software then, what else would be more noble for it than being used as a parody tool for lin-
       guistical habits, stereotypes and trends of this foolish era?

       Principles of parody are focusing a ridiculous topic and eventually abstracting its rules and schemes (here in terms of a  grammar  defini-
       tion) by which reproducing it through the variatio device.

       And randomization is perfect at this purpose thanks to its purely asemantic behaviour =:)

OPTIONS

       Please run polygen without parameters for an explanation on how to run polygen.

NAME

       yacc - yet another compiler-compiler

SYNOPSIS

       yacc [ -vd ] grammar

DESCRIPTION

       Yacc  converts  a  context-free grammar into a set of tables for a simple automaton which executes an LR(1) parsing algorithm.  The grammar
       may be ambiguous; specified precedence rules are used to break ambiguities.

       The output file, y.tab.c, must be compiled by the C compiler to produce a program yyparse.  This program must be loaded	with  the  lexical
       analyzer  program,  yylex,  as well as main and yyerror, an error handling routine.  These routines must be supplied by the user; Lex(1) is
       useful for creating lexical analyzers usable by yacc.

       If the -v flag is given, the file y.output is prepared, which contains a description of the parsing tables and a report on conflicts gener-
       ated by ambiguities in the grammar.

       If  the	-d  flag is used, the file y.tab.h is generated with the define statements that associate the yacc-assigned `token codes' with the
       user-declared `token names'.  This allows source files other than y.tab.c to access the token codes.

FILES

       y.output
       y.tab.c
       y.tab.h		   defines for token names
       yacc.tmp, yacc.acts temporary files
       /usr/share/misc/yaccparparser prototype for C programs

DIAGNOSTICS

       The number of reduce-reduce and shift-reduce conflicts is reported on the standard output; a more detailed report is found in the  y.output
       file.  Similarly, if some rules are not reachable from the start symbol, this is also reported.

BUGS

       Because file names are fixed, at most one yacc process can be active in a given directory at a time.
