 ## Escaping
 
 In order to ensure that arguments are handled consistently, this module
-writes a temporary script file containing the command as it exists in
-the package.json, followed by the user supplied arguments having been
-escaped to ensure they are processed as literal strings. We then instruct
-the shell to execute the script file, and when the process exits we remove
-the temporary file.
+passes the command from package.json and the extra arguments to
+`@npmcli/promise-spawn`. That module escapes the extra arguments for the
+selected shell, then runs the resulting command through the shell. The
+package script itself is not escaped, so shell operators in it still work.
 
 In Windows, when the shell is cmd, and when the initial command in the script
 is a known batch file (i.e. `something.cmd`) we double escape additional
 arguments so that the shim scripts npm installs work correctly.
