Implementation Details of GNU `gperf'
*************************************

   A paper describing the high-level description of the data structures
and algorithms used to implement `gperf' will soon be available.  This
paper is useful not only from a maintenance and enhancement perspective,
but also because they demonstrate several clever and useful programming
techniques, *e.g.*, `Iteration Number' boolean arrays, double hashing,
a "safe" and efficient method for reading arbitrarily long input from a
file, and a provably optimal algorithm for simultaneously determining
both the minimum and maximum elements in a list.
