	 * Export local DB to file.

	 * ## OPTIONS

	 * <output-file>
	 * : A file path to export to. Filename will be modified to end in .sql or
	 * .sql.gz if necessary.
	 *
	 * [--find=<strings>]
	 * : A comma separated list of strings to find when performing a string find
	 * and replace across the database.
	 *
	 *     Table names should be quoted as needed, i.e. when using a comma in the
	 *     find/replace string.
	 *
	 *     The --replace=<strings> argument should be used in conjunction to specify
	 *     the replace values for the strings found using this argument. The number
	 *     of strings specified in this argument should match the number passed into
	 *     --replace=<strings> argument.
	 *
	 * [--replace=<strings>]
	 * : A comma separated list of replace value strings to implement when
	 * performing a string find & replace across the database.
	 *
	 *     Should be used in conjunction with the --find=<strings> argument, see it's
	 *     documentation for further explanation of the find & replace functionality.
	 *
     * [--case-sensitive-find]
     * : A comma separated list of strings to find when performing a string find
     * and replace across the database.
     *
     * [--case-sensitive-replace]
     * : A comma separated list of replace value strings to implement when
     * performing a string find & replace across the database.
     *
	 * [--exclude-post-revisions]
	 * : Exclude post revisions from export.
	 *
	 * [--skip-replace-guids]
	 * : Do not perform a find & replace on the guid column in the wp_posts table.
	 *
	 * [--exclude-spam]
	 * : Exclude spam comments.
	 *
	 * [--gzip-file]
	 * : GZip compress export file.
	 *
	 * [--include-transients]
	 * : Include transients (temporary cached data).
	 *
	 * ## EXAMPLES
	 *
	 *     wp migratedb export ./migratedb.sql \
