JavaCup was created by Scott Hudson who is part of the Graphics Visualization and Usability Center and the College of Computing at Georgia Tech.
JavaCup is currently in its first alpha-test release (v0.9a). As such, it has not been extensively tested and you should use it at your own risk. However, it has been used to implement itself, and to create a Java parser which was able to successfully parse the full Java alpha2 release (and as of 10/10/95 we know of no bugs). We would greatly appreciate comments and bug reports (which can be sent to java-cup@cc.gatech.edu). However, we cannot offer any support at this time, and time available to us to pursue bug fixes is very limited.
