xtail - 2.1-11 main

xtail watches the growth of files. It's like running a "tail -f" on a bunch
of files at once. It notices if a file is truncated and starts from the
beginning. You can specify both filenames and directories on the command
line. If you specify a directory, it watches all the files in that directory.
It will notice when new files are created (and start watching them) or when
old files are deleted (and stop watching them).
.
Note that xtail isn't a graphical (X11) program, it runs on a plain tty. The
name likely comes from "eXtended tail" or such.
