script wanted: UNboxing database output

[Skaperen]

database tools typically put rows of data out in a boxed format. some can also output CSV and some cannot. i would like a script that can smartly read in such boxed format and unbox it, converting to CSV format. by "smartly" it should see where the box grid is a handle | and - and + characters in data, properly. is there such a tool around, written in Python?
