@subsection Parsing Long Options
To accept GNU-style long options as well as single-character options,
use @code{getopt_long} instead of @code{getopt}. You should make every
use @code{getopt_long} instead of @code{getopt}. This function is
declared in @file{getopt.h}, not @file{unistd.h}. You should make every
program accept long options if it uses any options, for this takes
little extra work and helps beginners remember how to use the program.
