I'm looking for a program to convert PowerPoint block diagrams to ASCII. I found Ditaa, which does the exact opposite of what I want done.

| | --+ block2+--> | |
| block | +-------+ |block3 |
| | | | | |

| Lots of work |

I also found FossilDraw, which does exactly what I want, but its speed perf leaves something to be desired.
