 ## Support
 This project is currently frozen. Therefore, I provide very limited support. I will not answer e-mails with comments about either stable or development versions (except for urgent issues from people with disabilities and copyright/acknowledgement issues: see "Third party resources used"). If you find any bugs or have any suggestions, feel free to report them in "Issues", but I cannot guarantee that I will respond to the reports within reasonable time.
