mmgen-cli: Communicate with a coin daemon via its JSON-RPC interface

opts_data = {
	'text': {
		'desc':    'Communicate with a coin daemon via its JSON-RPC interface',
		'usage':   '[opts] <command> <command args>',
		'options': """
-h, --help             Print this help message
--, --longhelp         Print help message for long (global) options
-a, --ascii-output     Ensure that output is ASCII encoded
-w, --wallet=NAME      Use tracking wallet with name NAME
""",
	'notes': """

The utility accepts all {pn} global configuration options and sources the user
config file, allowing users to preconfigure hosts, ports, passwords, datadirs,
tracking wallets and so forth, thus saving a great deal of typing at the
command line. This behavior may be overridden with the --skip-cfg-file option.

Arguments are given in JSON format, with lowercase ‘true’, ‘false’ and ‘null’
for booleans and None, and double-quoted strings in dicts and lists.
