Revision: 1.9
Committed: Sun Oct 19 02:03:02 2003 UTC (20 years, 7 months ago) by ats
Content type: text/plain
Branch: MAIN
Changes since 1.8: +13 -3 lines
Log Message:
Initial support for NetBSD. This adds NetBSD support for everything
except diskio stats (since they're even more disturbingly complex to get
at on NetBSD than the three OSs we already support). Tested against
NetBSD 1.6 on i386.
