Copy a file in a sane, safe and efficient way
...worth the extra cost. If we were doing it a lot, better to fall back on OS calls to the file system. I am sure boost has a copy file method in its filesystem class.
There is a C method for interacting with the file system:

int
copyfile(const char *from, const char *to...
