Welcome to your step-by-step journey for learning Argp, the GNU System's own command-line parsing facility. This book covers all aspects of Argp; from parsing simple command-line options to mixing sets of options from libraries into your own programs. The pace of this book is deliberately relaxed and focuses on incremental learning by example for beginner C programmers.
The book contains introductory information about command-line processing and then a series of 13 Argp programs that get increasingly challenging. Each program reveals more functionality of Argp.
