* cvs2svn is known to break binary files (images) which were not imported into the CVS with the -kb flag. Luckily Glynn fixed most of these some months ago.
See [[Talk:Migration_from_CVS_to_SVN|Discussion page]] for details.


* Files using keyword substitution, such as $Date$ in the description.html files, will have to have support for that enabled manually, once per file (or write a find routine with | xargs svn ...).
