-# many imports are lazy-loaded when they are needed
+# This module has many imports, quite a few of which are only
+# infrequently utilized. To reduce the initial overhead of
+# import this module, many of these imports are lazy-loaded
+# i.e. we only import the module when we use it
+# For example, we don't import the 'traceback' module
+# until the perror() function is called and the debug
+# setting is True
