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

Thus your program can now handle options such as:
myprog --input foo.c -o foo.o --no-tabs -i 100 *.class

Both long options (those that start with --) and short options (start with -
and consist of only one character) can be handled.
