Re: Question to svn merge (merge just parts of a diff)

Hi Bert,

first of all thank you for your response.

The following is exactly my case:
"If you have local changes, and then an update comes in with changes,
you have a different situation. In that case we start a merge operation,
that may or may not complete automatically depending on the combination
of local and remote changes. You can even configure your own 3-way-merge
tool to handle this merge step by your own tool in the config file."

Sorry, what do you mean with that? I can handle it by an own tool? You
mean an own script?

Best regards, Kai

If on update the local file is unmodified, the file is replaced by the new version. I can't think of a version management system that does this differently. No merging happens in this situation
