No idea. It seems to work just fine, though. |

Hm, how does one use MSV for conversion? There's little documentation |
| 12 |
included with the package. |

It would be nicer if these were released under a free software |
| 33 |
license. I don't think that http://bsp.mits.ch/download/lizenz |
| 34 |
qualifies (as it allows only private use and distribution at no |
| 35 |
charge). Sorry to be pedantic. |

Please correct me if I'm wrong, but my general impression is that |
| 41 |
the situation with respect to converters leaves much to be desired. |
| 42 |
At least, if we require a tool that is both well maintained and free |
| 43 |
software. |
