Usage:
    psalm-refactor [options] [symbol1] into [symbol2]

Options:
    -h, --help
        Display this help message

    --debug, --debug-by-line, --debug-emitted-issues
        Debug information

    -c, --config=psalm.xml
        Path to a psalm.xml configuration file. Run psalm --init to create one.

    -r, --root
        If running Psalm globally you'll need to specify a project root. Defaults to cwd

    --threads=auto
        If greater than one, Psalm will run analysis on multiple threads, speeding things up.
        By default

    --move "[Identifier]" --into "[Class]"
        Moves the specified item into the class. More than one item can be moved into a class
        by passing a comma-separated list of values e.g.

        --move "Ns\Foo::bar,Ns\Foo::baz" --into "Biz\Bang\DestinationClass"

    --rename "[Identifier]" --to "[NewIdentifier]"
        Renames a specified item (e.g. method) and updates all references to it that Psalm can
        identify.
