-/// Helper class used to construct source-level debugging information.
-///
-/// The helper contains a notion of "current context", which is a
-/// DWARF descriptor object representing the scope (module, class,
-/// function, etc.) that currently encloses the definitions being
-/// emitted.
-///
-/// Initially, you should call setModule() to specify the target
-/// module. Descriptors which are generated will be inserted into
-/// this module. This also generates the initial set of anchor
-/// descriptors, if they have not already been created for the module.
-///
-/// Next, you should call createCompileUnitDescriptor() to create
-/// the descriptor for the current compilation unit. This method
-/// sets the current context to the newly created descriptor.
-///
-/// Once that has been done, you can then create descriptors for
-/// global definitions (functions, variables, etc.). You can use
-/// setContext() to modify the current context. setContext() returns
-/// a reference to the previous context, allowing easy restoration
-/// of the previous context.
