+Generates perfect hash functions for sets of keywords

devel/gperf/pkg-descr

@@ -0,0 +1,24 @@
+While teaching a data structures course at University of California,
+Irvine, I developed a program called GPERF that generates perfect hash
+functions for sets of key words.  A perfect hash function is simply:
+
+          A hash function and a data structure that allows 
+          recognition of a key word in a set of words using 
+          exactly 1 probe into the data structure.
+
+The gperf.texinfo file explains how the program works, the form of the
+input, what options are available, and hints on choosing the best
+options for particular key word sets.  The texinfo file is readable
+both via the GNU emacs `info' command, and is also suitable for
+typesetting with TeX.
+
+The enclosed Makefile creates the executable program ``gperf'' and
+also runs some tests.
+
+Output from the GPERF program is used to recognize reserved words in
+the GNU C, GNU C++, and GNU Pascal compilers, as well as with the GNU
+indent program.
+
+Happy hacking!
