[REBOL] Patch for Cerebrus 1.0.3
From: gchiu::compkarori::co::nz at: 17-Nov-2002 11:31
Hi Guys,
Would those running Cerebrus 1.0.3 like to try this patch.
It downloads a 17Kb patch file, applies it to Cerebrus.exe
and creates new-cerebrus.exe.
When new-cerebrus.exe is run, it should copy itself over
cerebrus.exe, and when cerebrus.exe is then run, it
deletes new-cerebrus.exe.
This update facility was supposed to be automatic in 1.0.3
but something broke :( I'm hoping it will work after
this.
1.0.4 adds a cache directory overcoming the problems when
a POP client can not alter the time out period.
