- hooks for files (so file configuration entry, file configuration or something similar)
- XxxxModule modules merge to Xxxx modules
- check the mail sending -- currently probably mails by direct SMTP connection instead of sendmail
- consider switch directly to mail gem
- write correct YARD code documentation
- switch to 'find' standard library
- install should use Etc.sysconfdir, so remove the sys-uname dependency
- switch to IO#copy_stream for file copying
