-- This package provides some useful utility subprograms that provide access
|
|
-- to source code information known at compile time. These subprograms are
|
|
-- intrinsic operations that provide information known to the compiler in
|
|
-- a form that can be embedded into the source program for identification
|
|
-- and logging purposes. For example, an exception handler can print out
|
|
-- the name of the source file in which the exception is handled.
