 | 148 | tdb | 1.28 | University of Kent at Canterbury</a>, UK. The project was completed at | 
 
 
 
 
 | 149 |  |  | 4pm on 29 March 2001. It consisted of five lever-arch folders containing | 
 
 
 
 
 | 150 |  |  | mostly source code and documentation. The CVS repository was tagged to | 
 
 
 
 
 | 151 |  |  | signify this even, however, the project is still being developed by the |

 | 160 | pjm2 | 1.12 | feedback from our demonstation was more positive than we had | 
 
 
 
 
 
 
 
 | 161 | tdb | 1.27 | anticipated. We believe that the system may now be of interest |

 | 173 | tdb | 1.1 | It later became apparent that we had no name for our project (other |

 | 175 |  |  | the ice cream that had been oh-so-randomly drawn on the white board. | 
 
 
 
 
 | 176 |  |  | Copyright issues immediately ruled out anything involving Mr Whippy, |
