CUE Composer is a tool for working with CUESheets, the genesis of which was sparked by the lack of such software that was free, lest compatible with Linux.
It uses cuelib in order to work with CUE files, and as such should support extended sheets generated by rippers such as EAC and Morituri. Cuelib was originally written by Jan-Willem van den Broek (monstermanual@gmail.com) and appears to be unmaintained since late 2009. It is my hope that my work on CUE Composer will benefit Cuelib in that I will likely have to make bug fixes and close the open issues that were ported from gcode.
