Excluding these files from the commit only solves that problem temporarily, with the next commit these same files are again presented as changed files.
Removing these files from the local subversion administration is not hard, but each time I find myself searching again for the correct command, so today I decided to spent a blog on it, although the actual content is just a one-liner:
svn rm --keep-local
This will remove the file from subversion but will leave the files on the file system. This is quite useful with IDE files for instance.
