It is sometimes needed to remove files from the repository. SVN stores the whole history of the files, so deleting is not an irreversible step. Please be careful when deleting files though. A file may be needed for the build process, or can store important information for other people.
To remove a file, first delete the file from your local copy of the SVN module, and issue the following command:
$ svn remove file1 file2
This only schedules the file for removing. To complete the removing of the file(s), you need to do a commit, as described above.
