### 1.1 About This Document

The SASL (System Architecture Support Libraries) application provides support for:

- error logging
- alarm handling
- overload regulation
- release handling
- report browsing.

In this document, "SASL Error Logging" describes the error handler which produces the supervisor, progress, and crash reports which can be written to screen, or to a specified file. It also describes the report browser rb.

The chapters about release structure and release handling have been moved to OTP Design Principles.
