=head1 NAME

Alien::GvaScript - Gva extension to the prototype javascript framework

=head1 SYNOPSIS

  use Alien::GvaScript;
  ...
  $path    = Alien::GvaScript->path();
  ...
  Alien::GvaScript->install( $my_destination_directory );

=head1 DESCRIPTION

GvaScript (pronounce "gee-vascript") is a javascript framework 
born in Geneva, Switzerland (C<GVA> is the IATA code for 
Geneva Cointrin International Airport). 

It is built on top of the B<prototype>
object-oriented javascript framework (L<http://www.prototypejs.org>)
and offers a number of extensions and widgets, such as 
keymap handling, application-specific events, 
autocompletion on input field, tree navigation, and
forms with autofocus and repeated sections.
These functionalities are described in separate
documentation pages (see L<Alien::GvaScript::Intro>).

GvaScript is distributed using Perl tools, but the actual
content of the library is pure javascript; hence its 
location in the Alien namespace (see the L<Alien> manifesto).

GvaScript runtime library does not need Perl; you can integrate
it in any other Web programming framework. Perl is only needed for
developers who want to modify GvaScript sources and recreate a 
distribution package.



=head1 INSTALLATION

=head2 With usual Perl CPAN tools

Install C<Alien::GvaScript> just as any other CPAN module. Then you can 
write

  perl -MAlien::GvaScript -e "Alien::GvaScript->install('/my/web/directory')"

to copy the dthml files to your Web server.


=head2 Without Perl tools

Unzip and untar this distribution, then grab the 
files in F<lib/Alien/GvaScript/lib> subdirectory
and copy them to your Web server. 


=head2 Note about the documentation

The documentation sources are written in Perl's "POD" format.
An HTML version is automatically generated and included
in this distribution, under the F<lib/Alien/GvaScript/html> directory;
this documentation uses GvaScript's I<treeNavigator> widget 
for easier browsing.

If this distribution is installed as a CPAN module, then
another HTML version will probably be generated automatically
by your CPAN tool (but without the I<treeNavigator> widget).


=head1 METHODS

=head2 path

Returns the directory where GvaScript files are stored.

=head2 html

Returns the directory where GvaScript documentation
is stored.

=head2 install

Copies GvaScript files into the directory supplied as argument
