Sorry, but not so easy. The source code has a 19,000 byte table
of suffixes, and there is a binary encoded digram table.
Neither is user-accessible in the binary code.  We test the
algorithm by forcing the line length to something wee (.2 inches),
run a dictionary through it, and compare to a previously
hyphenated dictionary.
For DWB 3.2 we are adding the TeX hyphenation algorithm as a
user-selectable alternative. Seems to be more accurate, if
slower and larger, but may not be any more predictable.
If it's any consolation, either algorithm does better
than most people.
