	Name:      `y2j`,
	Summary:   `convert basic YAML to JSON`,
	Usage:     `[help|<file>]`,
	Comp:      compfile.New(),
	Version:   `v0.5.0`,
	Copyright: `Copyright 2021 Robert S Muhlestein`,
	License:   `Apache-2.0`,
	Commands:  []*Z.Cmd{help.Cmd},

	Description: `
		The {{cmd .Name}} command converts YAML (including references and
		anchors) to compressed JSON (with a single training newline) using
		the popular Go yaml.v3 package and its special <yaml:",inline"> tag.
		Because of this only YAML maps are supported as a base type (no
		arrays). An array can easily be done as the value of a map key.

		If no filename is passed standard input is assumed.

		JSON encoding is done using rwxrob/json instead of the "standard"
		encoding/json which unnecessarily escapes HTML characters by
		default.

		If h or help are passed as the first argument this help is assumed
		(preventing the uncommon use of files named 'h' or 'help').

		The intent of {{cmd .Name}} is to get YAML into a form quickly for
		using with the more powerful jq command line utility until an
		equally powerful yaml alternative is available.
