Apps in Elefant have a standard of placing configurations in a conf/config.php file inside the app's folder. This file should be INI-formatted.
For example, here's the configuration file for the wiki app:
; <?php /*
[Wiki]
edit_level = admin
;edit_level = member
layout = default
[Admin]
handler = wiki/index
name = Wiki
install = wiki/install
upgrade = wiki/upgrade
version = 0.9-beta
; */ ?>
And here's a longer example, from the blog app:
; <?php /*
[Blog]
; This is the title of your blog index page (/blog).
title = Blog
; This is the layout to use for blog listing pages.
layout = default
; This is the layout to use for the blog post page.
post_layout = default
; This is the service to use for blog comments. Currently
; only facebook is supported. Set it to Off to disable
; comments.
comments = facebook
[Twitter]
; Set these to your twitter credentials to have blog posts automatically
; tweeted to your twitter account.
username = """"
password = """"
[Custom Handlers]
; You can override some of the built-in handlers with your own
; by changing them here. You can also disable any of them by setting
; them to Off.
blog/index = blog/index
blog/post = blog/post
[Admin]
handler = blog/admin
name = Blog Posts
; */ ?>
