.SH NAME
STDLIB \- The STDLIB application.
.SH DESCRIPTION
.LP
The STDLIB application is mandatory in the sense that the minimal system based on Erlang/OTP consists of Kernel and STDLIB\&. The STDLIB application contains no services\&.
.SH "CONFIGURATION"

.LP
The following configuration parameters are defined for the STDLIB application\&. For more information about configuration parameters, see the \fIapp(5)\fR\& module in Kernel\&.
