+CPP supports two more ways of indicating that a header file should be

+that @samp{#import} is standard practice in Objective-C.
+
+@findex #import
+CPP supports a variant of @samp{#include} called @samp{#import} which
+includes a file, but does so at most once.  If you use @samp{#import}
+instead of @samp{#include}, then you don't need the conditionals
+inside the header file to prevent multiple inclusion of the contents.
+@samp{#import} is standard in Objective-C, but is considered a
+deprecated extension in C and C++.
+
+@samp{#import} is not a well designed feature.  It requires the users of
+a header file to know that it should only be included once.  It is much
+better for the header file's implementor to write the file so that users
+don't need to know this.  Using a wrapper @samp{#ifndef} accomplishes
+this goal.
+
+In the present implementation, a single use of @samp{#import} will
+prevent the file from ever being read again, by either @samp{#import} or
+@samp{#include}.  You should not rely on this; do not use both
+@samp{#import} and @samp{#include} to refer to the same header file.
+
+Another way to prevent a header file from being included more than once
+is with the @samp{#pragma once} directive.  If @samp{#pragma once} is
+seen when scanning a header file, that file will never be read again, no
+matter what.
+
+@samp{#pragma once} does not have the problems that @samp{#import} does,
+but it is not recognized by all preprocessors, so you cannot rely on it
+in a portable program.
