// (where SOURCE is a file, an http(s) URL, or '-' for standard input)
//
//Options:
// -h --help Print help
// -o --output OUTPUT_FILE Output to OUTPUT_FILE
// -p --properties PROPS... Output specific properties of the parsed article
// -V --version Print version
// -u --url Set the document URL when parsing standard input or a local file (this affects relative links)
// -U --is-url Interpret SOURCE as a URL rather than file name
// -q --quiet Don't output extra information to stderr
// -l --low-confidence MODE What to do if Readability.js is uncertain about what the core content actually is
//
//
//The --low-confidence option determines what should be done for documents where Readability can't tell what the core content is:
// no-op When unsure, don't touch the HTML, output as-is. If the --properties option is used, this will make the program crash.
// force Process the document even when unsure (may produce really bad output).
// exit When unsure, exit with an error.
//
//Default value is "no-op".

//
//The --properties option accepts a comma-separated list of values (with no spaces in-between). Suitable values are:
// html-title Outputs the article's title, wrapped in an <h1> tag.
// title Outputs the title in the format "Title: $TITLE".
// excerpt Article description, or short excerpt from the content, in the format "Excerpt: $EXCERPT"
// byline Author metadata, in the format "Author: $AUTHOR"
// length Length of the article in characters, in the format "Length: $LENGTH"
// dir Content direction, is either "Direction: ltr" or "Direction: rtl"
// html-content Outputs the article's main content as HTML.
// text-content Outputs the article's main content as plain text.

//Text-content and Html-content are mutually exclusive, and are always printed last.
