# 1.2. Authors

kppp is derived from ezppp 0.6 from Jay Painter. However, nearly everything in kppp was rewritten and so ezppp and kppp do not have very much in common.

The main authors are:

- `Bernd Johannes Wuebben` wuebben@kde.org

- `Mario Weilguni` mweilguni@sime.com

- `Harri Porten` porten@kde.org

Many thanks to the following people who have contributed code to kppp

- Jesus Fuentes Saaverdra for implementing several options and miscellaneous work.

- Markus Wuebben for the ATI query dialog.

- Peter Silva for pop up dialogs and other contributions.

- Martin A. Brown for proofreading some English text in the program

- Martin Häfner for the section on callback

- Olaf Kirch for the introduction to the mysteries of file descriptor passing.
