12.SH DESCRIPTION
13
14\fIgperf\fP reads a set of ``keys'' from \fIkeyfile\fP (or, by
15default, from the standard input) and attempts to find a non-minimal
16perfect hashing function that recognizes a member of the key set in
17constant, i.e., O(1), time. If such a function is found the program
18generates a pair of \fIC\fP source code routines that perform the
19hashing and table lookup. All generated code is directed to the
20standard output.
