/* This is a simple command-line option parser. Operation is similar to

* getopt_long(), except with a cleaner API.
|
||||
*
|
||||
* This is implemented in a single header file, as it's pretty small and you
|
||||
* generally only use an option parser in a single .c file in your program.
|
||||
*
|
||||
* Supports (examples from GNU tar(1)):
|
||||
* "--gzip"
|
||||
* "--file <arg>"
|
||||
* "--file=<arg>"
|
||||
* "-z"
|
||||
* "-f <arg>"
|
||||
* "-f<arg>"
|
||||
* "-zf <arg>"
|
||||
* "-zf<arg>"
|
||||
* "--" (To stop looking for further options)
|
||||
* "<arg>" (Non-option arguments)
|
||||
*
|
||||
* Issues/non-features:
|
||||
* - An option either requires an argument or it doesn't.
|
||||
* - No way to specify how often an option can/should be used.
|
||||
* - No way to specify the type of an argument (filename/integer/enum/whatever)
