$is_big_endian = unpack("h*", pack("s", 1)) =~ /01/;
- $is_litte_endian = unpack("h*", pack("s", 1)) =~ /^1/;
+ $is_little_endian = unpack("h*", pack("s", 1)) =~ /^1/;
Differing widths can cause truncation even between platforms of equal
endianness. The platform of shorter width loses the upper parts of the
notion of a "path" to uniquely identify a file on the system. How
that path is really written, though, differs considerably.

+Although similar, file path specifications differ between Unix,

Unix, for example, is one of the few OSes that has the elegant idea
of a single root directory.
