-/* The purpose of this util is just to finish packaging the
-   description into a static codebook.  It used to count hits for a
-   histogram, but I've divorced that out to add some flexibility (it
-   currently generates an equal probability codebook)
-
-   command line:
-   latticebuild description.vql
-
-   the lattice description file contains two lines:
-
-   <n> <dim> <multiplicitavep> <sequentialp>
-   <value_0> <value_1> <value_2> ... <value_n-1>
-
-   a threshmap (or pigeonmap) struct is generated by latticehint;
-   there are fun tricks one can do with the threshmap and cascades,
-   but the utils don't know them...
-
-   entropy encoding is done by feeding an entry list collected from a
-   training set and feeding it to latticetune along with the book.
-
-   latticebuild produces a codebook on stdout */
