- SPEC file cleanup
- Init script cleanup
- Removed some examples because of licensing issues. Upstream has clarified
and changed most of the license tags to GPLv2. Additionally, upstream
will include the examples in the next release.
- Removed a provide statement since a period was in the name and no other
package required that special name.
