========================================

SYNOPSIS
      #!/usr/bin/perl 
      use strict;
      use Lemonldap::Config::Parameters;
      use Data::Dumper;
      my $nconfig= Lemonldap::Config::Parameters->new(
                                 file  =>'applications.xml',
                                 cache => 'CONF' );
      my $conf= $nconfig->getAllConfig;
      my $cg=$nconfig->getDomain('appli.cp');
      my $ligne= $cg;
      print Dumper( $ligne);
      my $e = $cg->{templates_options} ;
      my $opt= "templates_dir";
      my $va = $cg->{$opt};
      my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;

     or by API :

     Lemonldap::Config::Parameters::f_delete('CONF');

     or by command line 

     perl -e "use Lemonldap::Config::Parameters;
    Lemonldap::Config::Parameters::f_delete('CONF');"
  
DESCRIPTION
    Lemonldap is a SSO system under GPL.

    Login page , handlers must retrieve their configs in an unique file eg
    :"applications.xml".

    This file has a XML structrure. The parsing phase may be heavy, so
    lemonldap can cache the result of parsing in memory with IPC. For
    activing the cache you must have in the config :

     <cache id="CONF" ConfigTtl="1000"> 
     </cache>
    with :  name='CONF' it's the  GLUE value : four letters (see  IPC::Shareable
    documentation).
            ttl: time to live in second   ( 0 for not reload ) 
     if ttl is too short the config file will be reload very offen .
  
     You can force the reload by command line  

     perl -e "use Lemonldap::Config::Parameters;
     Lemonldap::Config::Parameters::f_reload('CONF');"

     or 

     perl -e "use Lemonldap::Config::Parameters;
     Lemonldap::Config::Parameters::f_delete('CONF');"

    or perl -e "use Lemonldap::Config::Parameters;
    Parameters::f_reload('CONF');"

     WITHOUT CACHE SPECIFICATION , LEMONLDAP DOESN'T USE CACHE ! It  will read and
    parse config file each time.
 
METHODS
  new  (file  =>'/foo/my_xml_file.xml' ,
                 cache => 'CONF' );  # with IPC cache
     or 
            new(file  =>'/foo/my_xml_file.xml');     # without IPC  cache

  getAllConfig
     Return the  reference of hash  storing whole the config.

  getDomain('foo.bar')
     Return the reference of hash of config for domain  
     If the config file has only one domain , domain may bo omit .  

    eg : for the xml config file : <domain name="foo.bar" cookie=".foo.bar"
    path ="/" templates_dir="/opt/apache/portail/templates"
    templates_options = "ABSOLUTE => '1', INCLUDE_PATH => 'templates_dir'"
    login ="http://cportail.foo.bar/portail/accueil.pl" menu=
    "http://cportail.foo.bar/portail/application.pl" ldap_server
    ="cpldap.foo.bar" ldap_port="389" DnManager= "cn=Directory Manager"
    passwordManager="secret" branch_people="ou=mefi,dc=foo,dc=bar"
    session="memcached" > </domain>

        my $cg = $nconfig->getDomain();

     DB<2> x $cg
      0  HASH(0x89b108c)
       'DnManager' => 'cn=Directory Manager'
       'branch_people' => 'ou=mefi,dc=foo,dc=bar'
       'cookie' => '.foo.bar'
       'ldap_port' => 389
       'ldap_server' => 'cpldap.foo.bar'
       'login' => 'http://cportail.foo.bar/portail/accueil.pl'
       'menu' => 'http://cportail.foo.bar/portail/application.pl'
       'passwordManager' => 'secret'
       'path' => '/'
       'session' => 'memcached'
       'templates_dir' => '/opt/apache/portail/templates'
       'templates_options' => 'ABSOLUTE => \'1\', INCLUDE_PATH => \'templates_dir\'

  ref_of_hash : formateLineHash(string:line);
         or  formateLineHash(string:line,string:motif,string:key);

     Return a anonyme reference on  hash  and may replace the motif in the value of
    key by the value of another key  :

     eg 

     my $e = $cg->{templates_options} ;
     my $opt= "templates_dir";
     my $va = $cg->{$opt};
     my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;

     gives :  
      DB<1> x $ligne
     0  HASH(0x848b778)
       'ABSOLUTE' => 1
       'INCLUDE_PATH' => '/opt/apache/portail/templates'

      $ligne can be use directly like option for somes instructions

  ref_of_array : formateLineArray(string:line);
or  formateLineArray(string:line,string:motif,string:key);
    Return a anonyme reference on array and may replace the motif in the
    element by the value of another key :

      the return value can be use directly like option for somes instructions

  findParagraph(chapter[,section])
    Find and return a reference of chapter finds in xml file , a section can
    be specified.

Functions
  Lemonldap::Config::Parameters::f_delete('CONF');

  Lemonldap::Config::Parameters::f_reload('CONF');
     The next acces on cache will need to read file before .

  Lemonldap::Config::Parameters::f_dump('CONF');
     Dump of the config
