Upon the first invocation, trackcat prints the content of a given file
to STDOUT. It keeps track of the file's length, and upon the next call,
it will only print newly appendend lines.
The current cursor position within the tracked file will be stored
on a separate file on disk.
The name of the tracker file can be defined with the -t option.
By default, the tracker file is going to be located in
the same directory as the original file, under the name
.file.tracker if file is the original file name.
