37 ; - cli, first pass, read things in, bottom of the screen,
38 ; - just use getstr with a limit to be something like screen width - 10 for now
39 ; - print what the user inputted, dont' bomb on error messages, give target for show
40 ; - for overly long printing, go ahead and truncate with "..."
41 ; - for info, this should put out a simple message about the program, maintainer, purpose, links, etc
