.SH "Detailed Description"
.PP 
Base class for all library exceptions\&. 

This is the base class for all exceptions thrown by the standard library, and by certain language expressions\&. You are free to derive your own exception classes, or use a different hierarchy, or to throw non-class data (e\&.g\&., fundamental types)\&.
