+ Information about the cause of the build error:
+ -----------------------------------------------

+
+ status : the return code of the action that caused the build
+ error. Must be set to a non-zero value even if the
+ build error is not due to an action returning a
+ non-zero returned code.
+
+ exitstatus : SCons exit status due to this build error.
+ Must be nonzero unless due to an explicit Exit()
+ call. Not always the same as status, since
+ actions return a status code that should be
+ respected, but SCons typically exits with 2
+ irrespective of the return value of the failed
+ action.
+
+ filename : The name of the file or directory that caused the
+ build error. Set to None if no files are associated with
+ this error. This might be different from the target
+ being built. For example, failure to create the
+ directory in which the target file will appear. It
+ can be None if the error is not due to a particular
+ filename.
+
+ exc_info : Info about exception that caused the build
+ error. Set to (None, None, None) if this build
+ error is not due to an exception.
+
+
+ Information about the cause of the location of the error:
+ ---------------------------------------------------------
+
+ node : the error occured while building this target node(s)
+
+ executor : the executor that caused the build to fail (might
+ be None if the build failures is not due to the
+ executor failing)
+
+ action : the action that caused the build to fail (might be
+ None if the build failures is not due to the an
