RE: A standard package for config files is needed

Aonix had an Ada compiler for DOS that used a command language called
AdaWorld. I would hazard that an Ada J code compiler could have packages
with the same functionality. It might be a little verbose. However, this
might be useful for those of us who are Ada users rather than providers.

The Java Property class is simple and easy to use! The Properties
can be stored as an ASCI File, which is a  List of (Key,Value) pairs.
The Ada Version should be a bit more powerfull. e.g store
triples of (Scope,Key,Value), may be in be form you described
above: Scope.Key=Value

The Java Interfaces may be a starting point!

String getProperty(String key)
Searches for the property with the specified key in this property list.
     
String getProperty(String key, String defaultValue) 
Searches for the property with the specified key in this property list.
        
void list(PrintStream out) 
Prints this property list out to the specified output stream.
    
void list(PrintWriter out) 
Prints this property list out to the specified output stream.

void
load(InputStream inStream) 
Reads a property list (key and element pairs) from the input stream.

Enumeration propertyNames() 
Returns an enumeration of all the keys in this property list, 
including the keys in the default property list.

Object setProperty(String key, String value)
