-
--- This package provides an interface allowing to control *automatic* output
--- to standard error upon exception occurrences (as opposed to explicit
--- generation of traceback information using GNAT.Traceback).
---
--- This output includes the basic information associated with the exception
--- (name, message) as well as a backtrace of the call chain at the point
--- where the exception occurred. This backtrace is only output if the call
--- chain information is available, depending if the binder switch dedicated
--- to that purpose has been used or not.
---
--- The default backtrace is in the form of absolute code locations which may
--- be converted to corresponding source locations using the addr2line utility
--- or from within GDB. Please refer to GNAT.Traceback for information about
--- what is necessary to be able to exploit thisg possibility.
---
--- The backtrace output can also be customized by way of a "decorator" which
--- may return any string output in association with a provided call chain.
