Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
** version.
|
|
**
|
|
** The original driver has been written for 386bsd and FreeBSD by
|
|
** Wolfgang Stanglmeier <wolf@cologne.de>
|
|
** Stefan Esser <se@mi.Uni-Koeln.de>
|
|
