Ruby cp_r caveat

The ruby fileutil function cp_r, copies a directory, all of its files and subdirectories to a target location.  This is very useful when you are trying to sync 2 directories.  However, by default it will copy the directory as a subdirectory of the supplied target directory.  So:

cp_r "c:\\fly", "c:\\soup"

would give you:

"c:\\soup\\fly"

Now you have a fly in your soup.  This is a serious problem.  What if you were trying to sync your stick and donkey folders?

To get around this, just stick a period at the end of the the original directory path.  Like so:

cr_r "c:\\fly\\.", "c:\\soup"
