The AGFL formalism was first implemented between 1991 and 1996 with funding from the Dutch national research organization NWO. In the period 2000/2001, with financial support from the [NLnet foundation], the formalism has been revised in the light of experience and been brought under the GNU public licence.

Out of the many people who have contributed to the AGFL project we feel particularly obliged to Arend van Zwol, Arjan Knijff and Caspar Derksen who have spent years of their life on this elusive ideal parser generator.
