Revision 1.27, Fri Feb 2 21:36:00 2007 UTC (17 years, 6 months ago) by andrew
Branch: MAIN
Changes since 1.26: +85 -38 lines
Lots of good fixes in this one:
* fix tabs -> spaces
* more standardization on messages that are output
* allow for a complete retry of hosts that didn't work the first time
* allow passing hosts to check on the command line
