PUBLIC MARKS with tags tail & monitoring

ctail is like running tail -f, but can be used on multiple files. It uses the Curses library to split the screen into as many windows as there are files to watch. The size of each file's window can optionally be specified on the command line. Regular expressions can be used to display only lines matching (or not matching) arbitrary criteria. Each file's window has a status bar, showing the file name, date and time of last change and current file size.
