Vern Paxson wrote flex with the help of many ideas and much
inspiration from Van Jacobson.  Original version by Jef Poskanzer.

done by Van Jacobson.  The implementation was done by Kevin Gong and
Vern Paxson.

In 2001, W. L. Estes took over as maintainer of flex.

contributed a large number of new features, fixed a large number of
outstanding bugs and has made significant contributions to the flex
documentation.
