## Getopt::Long provides support for short versions with single "-" except for -v.
## Therefore all short versions were automatically included either with first letter
## or via an alias as for -a, -i, -o and -V.
##
## -v deserves special care due to the existence of support for $version within the
## Getopt module. Therefore -v is treated specially.
