-parseopts.sh:
-A getopt_long-like parser which portably supports longopts and shortopts
-with some GNU extensions. It does not allow for options with optional
-arguments. For both short and long opts, options requiring an argument
-should be suffixed with a colon. After the first argument containing
-the short opts, any number of valid long opts may be be passed. The end
-of the options delimiter must then be added, followed by the user arguments
-to the calling program.
-
-Recommended Usage:
- OPT_SHORT='fb:z'
- OPT_LONG=('foo' 'bar:' 'baz')
- if ! parseopts "$OPT_SHORT" "${OPT_LONG[@]}" -- "$@"; then
- exit 1
- fi
- set -- "${OPTRET[@]}"
-Returns:
- 0: parse success
- 1: parse failure (error message supplied)

human_to_size.sh:
A function to convert human readable sizes (such as "5.3 GiB") to raw byte
equivalents. base10 and base2 suffixes are supported, case sensitively. If
