I know about the svn:ignore property, but that doesn't solve my problem.
I have a source directory. I want to create a directory inside it, called "build" that I will build inside. I don't want to put "build" in svn:ignore because other people using the same repository don't need it ignored, and I may want to have different names for this.
The general problem is this:
Given a working copy of a subversion directory, I want to make a subdirectory that will be ignored by svn without modifying anything on the server. If I could make a directory and stick an empty ".svn_ignore_this_directory" file inside it or something, that would be awesome. I think in git it would be something like making a .gitignore file with just "." in it, but maybe that's not right. Can svn do this?
