Announcing UEX: UltraEdit for Linux (Now in Beta testing)

UltraEdit is heralded by the Windows community as the ideal text, HTML, HEX editor, advanced PHP, Perl, Java and JavaScript editor for programmers. We think delivering anything short of this to our Linux/Mac users would be a disappointment. As such, we didn't simply port UltraEdit (Windows) to Linux, rather we re-engineered the critical components to take advantage of the native Linux/Mac operating system - all this to give you the superior performance that UltraEdit is known for - on your operating system of choice.
