Patrick J Volkerding 5a12e7c134 Slackware 13.0 
Wed Aug 26 10:00:38 CDT 2009
Slackware 13.0 x86_64 is released as stable!  Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits.  The ISOs are off to the replicator.  This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com.  Please consider
picking up a copy to help support the project.  Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy!  -P.

+Description: Traces the route taken by packets over a TCP/IP network.
+ The traceroute utility displays the route used by IP packets on their way to a
+ specified network (or Internet) host. Traceroute displays the IP number and
+ host name (if possible) of the machines along the route taken by the packets.
+ Traceroute is used as a network debugging tool. If you're having network
+ connectivity problems, traceroute will show you where the trouble is coming
+ from along the route.
+ .
+ Install traceroute if you need a tool for diagnosing network connectivity
+ problems.
