Help Macros and Plugins with trac.ini lookup and defaulting
By itself, this modules does not provide any functionality. This module provides a helper class which can be used by other plugins, especially macros, in retrieving optional arguments from trac.ini.
A macro using this module, can be called with a config=xxx option, to retrieve a set of options which in trac.ini all start with prefix xxx. Inheritance is supported, by writing an option xxx.inherit = yyy in trac.ini - all macro options not yet determined, are then searched with the other prefix, yyy. Multiple inheritance is supported, by writing config=prefixA|prefixB in the macro invocation, or writing an xxx.inherit = prefixC|prefixD option in trac.ini The macro module which uses this functionality, specifies a list of expected options, as well as their defaults. These defaults will then be used when the respective option is specified nowhere.
Right now, as this is brand new, no plugin / macro uses the functionality. There is an examlemacro.py file included in the distribution, which when enabled through the admin plugings interface, provides a macro named TracMacroConfigExample, which displays a table detailling various interesting things about concrete option lookups. This allows you to play with macro arguments and in a corresponding [macroconfig-example] section in trac.ini, to play with inheritance setups.
This is how exemplary calls to that macro would be written in a wiki page:
[[TracMacroConfigExample(config=class-c, extra=more stuff)]]
Use this together with a trac.ini section like this:
[macroconfig-example] class-a.bool = True class-a.text = A Text class-b.bool = False class-b.int = 73 class-c.config = class-a|class-b class-c.list = knees|toes
If you have any issues, create a new ticket.

remember non-keyword macro args, provide list() method to retrieve them.

optional options() method parameter result=, possible values 'all' (default, as before), 'wellknown' (only return registered options), 'extra' (only return extra options), or 'nothing' (do not return anything)
