A student's working on a program that identifies poetic forms and produces stats. Later it will looks at irregular sound effects too. The program should be freely available this summer. A progress report is on

Comments and suggestions welcomed.
One of the "forms" it detects is free-verse's "Boxed Form" - a poem of at least 3 stanzas where all lines are roughly the same length and all stanzas (except perhaps the final one) have the same number of lines. Line-length tolerance is adjustable: by default it's 20%.
