devel/gengetopt 2.23.1 FreeBSD

This program generate a C function that uses getopt_long function to parse the command line options, validate them and fill a struct.

Thus your program can now handle options such as:

myprog --input foo.c -o foo.o --no-tabs -i 100 \*.class

And both long options (those that start with --) and short options (start with - and consist of only one character) can be handled. For standards about short and long options you may want to take a look at the GNU Coding Standards.
