INTRODUCTION

The DELTA format (DEscription Language for TAxonomy) is a flexible method
for encoding taxonomic descriptions for computer processing. DELTA-format
data can be used to produce natural-language descriptions, conventional and
interactive keys, and cladistic and phenetic classifications.

The DELTA System supplied by the CSIRO Division of Entomology comprises:
Intkey, a program for interactive identification and information retrieval;
Confor, a program for translating DELTA data into other formats; various
other programs; documentation, including User's Guide to the DELTA System
and A Primer for the DELTA System; and sample data files.
