Parse::Eyapp uses and modifies all the files in the Parse::Yapp 1.05
distribution.

IMPORTANT NOTES

The main source of documentation is  Parse::Eyapp (Reference guide).
Have a look at the tests, they can help you. 
Not all the examples in the examples/ directory work.

The eyapp frontend has its own documentation using either 'perldoc eyapp'
or (on systems with man pages) 'man eyapp'.

The trereg frontend to Parse::Eyapp::Treeregexp has its own documentation 
using either 'perldoc treereg' or (on systems with man pages) 'man treereg'.

Any help on improving those documentations is very welcome.

DESCRIPTION

This is alpha release 1.067 of the Parse::Eyapp parser generator.

Parse::Eyapp (Extended yapp) is a collection of modules
that extends Francois Desarmenien Parse::Yapp 1.05.
Eyapp extends yacc/yapp syntax with
functionalities like named attributes,
EBNF-like expressions, modifiable default action,
automatic syntax tree building,
semi-automatic abstract syntax tree building,
translation schemes, tree regular expressions,
tree transformations, scope analysis, support,
directed acyclic graphs and a few more.

REQUIREMENTS

Requires perl5.6 or higher

You need the following modules:

                     List::Util  
                     Data::Dumper
                     Pod::Usage 

The last three belong to the core of recent Perl distributions.
Some of the tests make use of:

Test::Exception
Test::Warning
Test::Pod

The tests related with those modules are skipped if you haven't installed
those modules. 

If you decided to install Test::Warn be aware that
Test::Warn depends on  Array::Compare. My experience is that you must 
install Array::Compare by hand first (i.e. perl Makefile.PL; make; make test; make install)
and then go to install Test::Warn.

INSTALLATION

perl Makefile.PL
make
make test
make install

LEARNING TO USE IT

- Make a local copy of the examples/ directory in this distribution
- Probably it will be also a good idea to make a copy of the tests in the t/ directory.
  They also illustrate the use of Eyapp
- Get the pdf files in 
     http://nereida.deioc.ull.es/~pl/perlexamples/Eyapp.pdf

- Print Eyapp.pdf.

WARRANTY

This software comes with absolutely NO WARRANTY of any kind. 
I just hope it can be useful.
