'-u' - MAKE FILE NAMES UPPER CASE

This option causes all file names to be converted to upper case.

If adding files to archives, the names of all files added will be stored in
upper case.  If extracting from archives, all files will be extracted using
upper case file names.  If viewing or listing archives, all files will be
shown as having upper case file names even if this is in fact not the case.
