FileHandle::Unget operates exactly the same as FileHandle, except that it provides a version of ungetc that allows you to unget more than one character. It also provides ungets to unget a string.
This module is useful if the filehandle refers to a stream for which you can't just 'seek()' backwards. Some operating systems support multi-byte 'ungetc()', but this is not guaranteed. Use this module if you want a portable solution. In addition, on some operating systems, eof() will not be reset if you ungetc after having read to the end of the file.
NOTE: Using 'sysread()' with 'ungetc()' and other buffering functions is still a bad idea.
