Set svn to ignore auxiliary LaTeX files globally

There are certain intemediary files (.aux, .log, etc.) that are best not put under version control because they change very often. In SVN, to stop svn status complain about them, you can add those patterns to the global-ignores property in your ~/.subversion/config file (or "%APPDATA%\Subversion\config" on Windows).

If you just want to set it for one repository, you can use svn propedit svn:ignore . or svn propset as explained here.
