[Courses] [C] getopt() and getopt_long()

[Anand R]

Hi Team,

	Could we have a discussion on using parsing command line arguments.
Typically, we have programs today, that use getopt() and getopt_long() for
parsing command line arguments (they have made life a lot more easier for
us). A small discussion on best practices, cute hacks and
guidelines/pitfalls/best practices would be really useful and would greatly
benefit newbies. 

Thanks,
Andy
