Re: Error During Repository Load

What is the error that SVN reports you about?

You can use the following attached python script getDumpRev.py to
get the contents of a certain revision, but you need to have python
installed on your system.

It must be launched this way:

./getDumpRev.py pathToDumpFile revStart revEnd

Say, if you want to get the contents of revision 1, then

launch the script in the following way:

./getDumpRev.py dump2 1 2
