Looping through an array of strings:
	Let's set up an example, with C

Could we just make a vector of C++ strings?
	Sure
	Now == works

Argument types:
	flags
	arguments

There are libraries here
	It's a bunch of extra work for lab 9
	lurk components example
	Really old goat facts example

As far as I know, there isn't a manual page for argp_parse
	It's documented in the glibc documentation, here:
	https://sourceware.org/glibc/manual/2.42/html_mono/libc.html#Argp

getopt:  also used a lot
	Doesn't auto-generate --help, but works pretty good too

Lab 9:
	You can use the library, or just do it manually
