-/**
- * Implements hook_drush_engine_ENGINE_TYPE().

- * The output format types supported are represented by
- * the 'engine-capabilities' of the output format engine.
- * The different capabilities include:
- *
- * format-single: A simple string.
- *
- * format-list: An associative array where the key
- * is usually the row label, and the value
- * is a simple string. Some list formatters
- * render the label, and others (like
- * "list" and "csv") throw it away.
- *
- * format-table: An associative array, where the key
- * is the row id, and the value is the
- * column data. The column data is also
- * an associative array where the key
- * is the column id and the value is the
- * cell data. The cell data should usually
- * be a simple string; however, some
- * formatters can recursively format their
- * cell contents before rendering (e.g. if
- * a cell contains a list of items in an array).
- *
- * These definitions align with the declared 'output-data-type'
- * declared in command records. @see drush_parse_command().
- *
- * Any output format that does not declare any engine capabilities
- * is expected to be able to render any php data structure that is
- * passed to it.
