Subject Re: missing sha-1 after svndumptool
Date Fri, 15 Jun 2012 10:54:38 GMT
Thanks Steve,

That's really useful. In that case we shall carry on with our migration 
using svndumptool.

We are aware it's a third party application, but since it affects our 
Subversion dump files we thought that you guys would be better placed to 
answer whether this would cause an issue with usage of the output dump 
files.

It sounds like the MD5 check sums are enough so that's good.

Thanks again for the swift response!

Russell
