Description:
Jules' Utility Class Extensions (module sources)
JUCE (Jules' Utility Class Extensions) is an all-encompassing C++ framework for developing cross-platform software. . It contains pretty much everything you're likely to need to create most applications, and is particularly well-suited for building highly-customised GUIs, and for handling graphics and sound. . This package provides the sources for the JUCE modules, as used by 'jucer' projects. (Projucer is provided in the 'juce-tools' package).
