Rather than hard-coding the VMNetX version in the man pages, we should be generating the man pages at build time.  You can change this, or I can do it if you prefer:

1. Rename `*.1` to `*.1.in`
2. Drop the `dist_` prefix
3. Add `*.1` to `CLEANFILES` and `*.1.in` to `EXTRA_DIST`
4. Replace the hardcoded versions in `*.1.in` with `@version@`
5. Add a Make rule, similar to the one for `vmnetx/system.py`, that substitutes `$(VERSION)` into `*.1.in`
6. Add `*.1` to `.gitignore`
