Quanta plus is a web development environment for working with html and associated languages. it strives to be neutral and transparent to all markup languages, while supporting popular web-based scripting languages, css and other emerging w3c recommendations.
quanta plus supports many external components, debuggers and other tools for web development, several of which are shipped with the kde web development module.
quanta plus is not in any way affiliated with any commercial versions of quanta. the primary coders from the original team left the gpl'd version to produce a commercial product.
this package is part of kde, as a component of the kde web development module. see the 'kde' and 'kdewebdev' packages for more information.
