modxslt-perror can be used to convert a numeric error number into a human readable string. All it does, is reading the specified error ERRNO from the command line, and convert it into a string using strerror.
modxslt-perror exists since modxslt and libmodxslt can be used from multithreaded application, but strerror is not reentrant and cannot be used directly.
