# Well this is a bloody kickass little app which tells you things which could
# really be obtained elsewhere, but what are you going to do 'eh! It walks a
# directory structure and collects the number of files, as well as their size,
# then prints whichever data you like. bla bla bla! The root directory will be
# the current working diectory unless you specify another location with the -d
# switch (good idea). One important thing to note is that data is easy to read
# because it will tell you what the numbers are for, except when using the -r
# switch which just spits the numbers out seperated by a space. In this case
# the numbers are in the same order.
