Catalyst Configure Schema

1, App class will load config option into self.
2, Other class query App class about its config option. For example, Model::DB will try to query its option in $config->{Model}->{DB}.
3, Catalyst default uses Config::General to load config from {app_name}.conf
4, Class can setup configure item in its source file by __PACKAGE__->config( {info} ), and this config function will return the current package level configure options.

Local config

By default, Catalyst try to local appname.conf, but it also try to load a local config file: appname_local.conf, which contains high priority value than appname.conf.
The __PACKAGE__->config() has lowest priority.

So use __PACKAGE__->config() to setup default configuration.
Use appname.conf to setup configure wish included into version manager system.
Use appname_local.conf to complete items in release mode.

User can use envoriment variable CONFIG_LOCAL_SUFFIX to change 'local' to other value.

Config::General config format

<name1> will map to a named field: $parent->{name1} = { value inside block }.
<name1 name2> will map to $parent->{name1}->{name2}
name = value will match to name=>value
name = value1
name = value2 will match to name => [ value1, value2 ]

var tag;
var func = function(){
return afunc( tag );
}

is not a correct usage.

The correct one is:

var genFunc = function( ptag ){
var ltag = ptag;
return function(){afunc( ltag )};
};

genFunc( tag );
