// ah yes, COBOL. what a throwback. for those that know
// then you know exactly what is in this file. For those that don't, here it is:

// All this does is output human readable text formatted to be viewable on
// a console with a fixed with font. AKA: a typerwriter. Which is exactly
// what COBOL did in the 1970's (60s? notsure) And the 80s.

// So, you want to dump out stuff on the console. Let's see. Something like

/*
	forge --favorites

	go.wit.com/apps/myapp          v0.2.0     (installed)
	go.wit.com/lib/somethingfun    v0.0.7     (not downloaded)
*/

// anyway, you get the idea. This is also called COBOL because it does on
// thing and truncates every line output to the columns you see with stty -a
// my monitor is huge, so it's not going to work at 80x24. 160x48 is better
// actually, I'd predict some of these will probably end up 240 wide
// long live good eyesight and 4K monitors!
