 When adding new files to the existing source code, always perform SVN Add and
then SVN Commit

15. LIMITAtions of svn
 Locking: Subversion currently has no support for file locking, to prevent more
than one person from working on single file.
 Subversion does not store the modification times of files.
 Subversion stores additional copies of data on the local machine, which can
become an issue with very large projects or files,
