+@defvar Objfile.have_debug_info
+A boolean indicating if debug information for the objfile is present.
+Note that a program compiled without @samp{-g} may still have some debug
+information, e.g., from the @code{C} runtime.  Thus a value of @code{True}
+for this attribute does not mean that debug information is present for
+every source file in the program.  It only means that debug information
+is present for at least one source file.
+@end defvar

 @defvar Objfile.progspace
 The containing program space of the objfile as a @code{gdb.Progspace}
 object.  @xref{Progspaces In Python}.
