SCM files in src/site directory cause 'mvn site' to fail - need to exclude files

Our SCM solution (Surround SCM) places .MySCMServerInfo files in each directory. For a site archetype (and possibly others), issuing a 'mvn site' after checking the project into SCM causes the error below to be generated. Need a way of excluding .MySCMServerInfo files from the site generator (or possibly ideally, restricting the document transformer to recognised file extensions).
