following the GNU standard.
.
./test -vo out.png --size 256 input.txt
.
with the following features:
.
* build-in help (-h and --help) message
* scan arguments into struct fields with configuration in tags
* scan into composite field types (arrays, slices, structs)
* allow for nested sub commands
.
GNU command line argument rules:
.
* arguments are options when they begin with a hyphen -
* multiple options can be combined: -abc is the same as -a -b -c
* long options start with two hyphens: --abc is one option
* option names are alphanumeric characters
* options can have a value: -a 1 means that a has value 1
* option values can be separated by a space, equal sign, or nothing: -a1 -
a=1 -a 1 are all equal
* options and non-options can be interleaved
* the argument -- terminates all options so that all following arguments
are treated as non-options
* a single - argument is a non-option usually used to mean standard in or
out streams
* options may be specified multiple times, only the last one determines
its value
* options can have multiple values: -a 1 2 3 means that a is an
array/slice/struct of three numbers of value [1,2,3]
