JInto is a plugin for Eclipse that lets the developer easily edit and maintain resource bundles (files that hold the localized strings for an application). It features parallel editing of all language versions (side by side), warnings when no text has been provided for a specific key, or when the text for one key is identical for different languages, and a search wizard to locate unused strings (strings that are referenced, but not actually defined in the resource bundle). It has been tested under Windows and Linux.

Style is the ongoing C++ port of IBM's SWT for Java, itself deriving from IBM's VisualAge for SmallTalk, with two major twists. First, it is written in 100% ISO-C++ with no specific compiler dependencies, and second, it comes with a threading model design that guarantee that users won't be stuck with busy cursors forever. It currently targets OS X, Win32, and GTK.
