But I was thinking that maybe the text could be rewritten for clarity
LibreCAD started as a project to build CAM capabilities into the
community version of QCad for use with a Mechmate CNC router.
Since QCad CE was built around the outdated Qt3 library, it had to be
ported to Qt4 before additional enhancements. This gave rise to CADuntu.
The project was known as CADuntu only for a couple of months before the
community decided that the name was inappropriate. After some discussion
within the community and research on existing names, CADuntu was renamed
Porting the rendering engine to Qt4 proved to be a large task, so
LibreCAD still does depend on the Qt3 support library, which is
gradually being changed.
