Branches: MAIN
CVS tags: HEAD

- Support for submission of files to externalresponse.
  - New routine: &portfiles_versioning() in lonnet.pm called after grading
    externalresponse to handle versioning of submitted files in portfolio.
  - &get_next_version(), &version_selected_portfile(), &file_name_version_ext()
    moved from grades.pm to lonnet.pm to facilitate re-use.
