GNU ccd2cue is a CCD sheet to CUE sheet converter. It supports the full extent of CUE sheet format expressiveness, including mixed-mode discs and CD-Text meta-data. It plays an important role for those who need to use optical disc data which is only available in the proprietary sheet format CCD, but don’t want to surrender their freedom. It fills an important gap in the free software world because before its conception it was impossible to use complex forms of optical disc data laid out by CCD sheets in a whole/holy free operating system.
The GNU ccd2cue documentation is also intended to be a reference documentation for both sheet format specifications. That way we can reverse engineer the secret CCD sheet proprietary format only once and then make the information available for developers in order to benefit all free software users that want their software to be interoperable. The CUE sheet format is not a secret, but with this package we take the opportunity to ensure that its specification is available under a free documentation license for the sake of the whole free software community.
