While it's probably not important to you at this time, the path you
built above will only work on Windows systems, where the file separator
character is backslash.  A path like that won't work on Unix-like
systems such as Linux and OSX.

It's a really good idea to use File.join or the pathname library to
build your paths rather than directly building path strings.  If you do,
you don't need to worry about the potential pitfalls if you ever decide
to take your script to another platform.  The tools should manage the
differences for you.

Another option is to always use forward slashes, if you really must
build the path strings directly.  For now at least, forward slashes
appear to work on every platform supported by Ruby, including Windows;
however, it's possible (if unlikely) that there may one day be a system
where this is not the case.  Using the tools mentioned above should give
you a better chance of being protected in such an event. :-)
