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!

7 | Gameport support is for the standard 15-pin PC gameport. If you | ||
8 | have a joystick, gamepad, gameport card, a soundcard with a gameport | ||
9 | or anything else that uses the gameport, say Y or M here and also to | ||
10 | at least one of the hardware specific drivers. | ||
11 | |||
12 | For Ensoniq AudioPCI (ES1370), AudioPCI 97 (ES1371), ESS Solo1, | ||
13 | S3 SonicVibes, Trident 4DWave, SiS7018, and ALi 5451 gameport | ||
14 | support is provided by the sound drivers, so you won't need any | ||
15 | from the below listed modules. You still need to say Y here. | ||
16 | |||
17 | If unsure, say Y. | ||
