This module is an addition to Drupal's Maintenance mode settings page.

It allows site administrators to set IP addresses that are allowed access to the website while in maintenance mode, without being logged in.

Mainly written as a means by which clients can easily review their website being developed without the hassle of logging in into an offline site.

Some helpful debugging functions I have been using for a few years now. I'm not sure if the original author (Jake Rockowitz) is still maintaining the module.

Drush Hooks for Git is a fork from GitHook. This fork exists because:

• GitHook uses a "plugins" system when it should really use the Drush hooks system.
• GitHook is designed to be self contained and fast which makes it hard to extend and not capable of bootstrapping Drupal
• To prevent breaking existing functionality for the GitHook extension

Maybe some day the two could be merged back together?

A port of jquery_update for d6 to support 1.7

Important

It should be noted that this is not compatible with Drupal 6 core. This will only work on pressflow which is using json_encode a php5 function. If you want to try doing that, please download this patch http://drupal.org/files/issues/drupal_to_js_proper_json-D6_0.patch and apply it to your common.inc file.

Git manager is a framework that provides a github-like functionality to a Drupal site.
Current features include

This module provides integration into Amazon SNS. It provides administrative interfaces for managing topics and publishing messages. It also incorporates some API functionality to publish messages for channels. This module is most useful for developers who maintain a network of independent Drupal sites and need a push mechanism to communicate system events.

The PHPExcel module allows developers to export/import data to/from real Excel files.

The idea behind this module is to have a single module for handling the export or import of Excel files, instead of multiple modules handling specific cases.

The module provides no functionality as-is (the .module file is as good as empty). The phpexcel.inc file must be included to use the export or import functions in your own module.

Changes the $node->nid value on existing content.
