+
+  Once a program is built,
+  it is often appropriate to install it in another
+  directory for public use.
+  You use the &Install; method 
+  to arrange for a program, or any other file,
+  to be copied into a destination directory:
+
+  </para>
+
+  <programlisting>
+     env = Environment()
+     hello = env.Program('hello.c')
+     env.Install('/usr/bin', hello)
+  </programlisting>
+
+  <para>
+
+  Note, however, that installing a file is
+  still considered a type of file "build."
+  This is important when you remember that
+  the default behavior of &SCons; is
+  to build files in or below the current directory.
+  If, as in the example above,
+  you are installing files in a directory
+  outside of the top-level &SConstruct; file's directory tree,
+  you must specify that directory
+  (or a higher directory, such as <literal>/</literal>)
+  for it to install anything there:
+
+  </para>
+
+  <screen>
+     % <userinput>scons -Q</userinput>
+     cc -o hello.o -c hello.c
+     cc -o hello hello.o
+     % <userinput>scons -Q /usr/bin</userinput>
+     Install file: "hello" as "/usr/bin/hello"
+  </screen>
+
+  <para>
+
+  It can, however, be cumbersome to remember
+  (and type) the specific destination directory
+  in which the program (or any other file)
+  should be installed.
+  This is an area where the &Alias;
+  function comes in handy,
+  allowing you, for example,
+  to create a pseudo-target named <literal>install</literal>
+  that can expand to the specified destination directory:
+
+  </para>
+
+  <programlisting>
+     env = Environment()
+     hello = env.Program('hello.c')
+     env.Install('/usr/bin', hello)
+     env.Alias('install', '/usr/bin')
+  </programlisting>
+
+  <para>
+
+  This then yields the more natural
+  ability to install the program
+  in its destination as follows:
+
+  </para>
+
+  <screen>
+     % <userinput>scons -Q</userinput>
+     cc -o hello.o -c hello.c
+     cc -o hello hello.o
+     % <userinput>scons -Q install</userinput>
+     Install file: "hello" as "/usr/bin/hello"
+  </screen>
+

+  <title>Installing Multiple Files in a Directory</title>
+
+    <para>
+
+    You can install multiple files into a directory
+    simply by calling the &Install; function multiple times:
+
+    </para>
+
+    <programlisting>
+       env = Environment()
+       hello = env.Program('hello.c')
+       goodbye = env.Program('goodbye.c')
+       env.Install('/usr/bin', hello)
+       env.Install('/usr/bin', goodbye)
+       env.Alias('install', '/usr/bin')
+    </programlisting>
+
+    <para>
+
+    Or, more succinctly, listing the multiple input
+    files in a list
+    (just like you can do with any other builder):
+
+    </para>
+
+    <programlisting>
+       env = Environment()
+       hello = env.Program('hello.c')
+       goodbye = env.Program('goodbye.c')
+       env.Install('/usr/bin', [hello, goodbye])
+       env.Alias('install', '/usr/bin')
+    </programlisting>
+
+    <para>
+
+    Either of these two examples yields:
+
+    </para>
+
+    <screen>
+       % <userinput>scons -Q install</userinput>
+       cc -o goodbye.o -c goodbye.c
+       cc -o goodbye goodbye.o
+       Install file: "goodbye" as "/usr/bin/goodbye"
+       cc -o hello.o -c hello.c
+       cc -o hello hello.o
+       Install file: "hello" as "/usr/bin/hello"
+    </screen>
+
+  </section>

+  <section>
+  <title>Installing a File Under a Different Name</title>
+
+    <para>
+
+    The &Install; method preserves the name
+    of the file when it is copied into the
+    destination directory.
+    If you need to change the name of the file
+    when you copy it, use the &InstallAs; function:
+
+    </para>
+
+    <programlisting>
+       env = Environment()
+       hello = env.Program('hello.c')
+       env.InstallAs('/usr/bin/hello-new', hello)
+       env.Alias('install', '/usr/bin')
+    </programlisting>
+
+    <para>
+
+    This installs the <literal>hello</literal>
+    program with the name <literal>hello-new</literal>
+    as follows:
+
+    </para>
+
+    <screen>
+       % <userinput>scons -Q install</userinput>
+       cc -o hello.o -c hello.c
+       cc -o hello hello.o
+       Install file: "hello" as "/usr/bin/hello-new"
+    </screen>
+
+  </section>
+
+  <section>
+  <title>Installing Multiple Files Under Different Names</title>
+
+    <para>
+
+    Lastly, if you have multiple files that all
+    need to be installed with different file names,
+    you can either call the &InstallAs; function
+    multiple times, or as a shorthand,
+    you can supply same-length lists
+    for both the target and source arguments:
+
+    </para>
+
+    <programlisting>
+       env = Environment()
+       hello = env.Program('hello.c')
+       goodbye = env.Program('goodbye.c')
+       env.InstallAs(['/usr/bin/hello-new',
+                      '/usr/bin/goodbye-new'],
+                     [hello, goodbye])
+       env.Alias('install', '/usr/bin')
+    </programlisting>
+
+    <para>
+
+    In this case, the &InstallAs; function
+    loops through both lists simultaneously,
+    and copies each source file into its corresponding
+    target file name:
+
+    </para>
+
+    <screen>
+       % <userinput>scons -Q install</userinput>
+       cc -o goodbye.o -c goodbye.c
+       cc -o goodbye goodbye.o
+       Install file: "goodbye" as "/usr/bin/goodbye-new"
+       cc -o hello.o -c hello.c
+       cc -o hello hello.o
+       Install file: "hello" as "/usr/bin/hello-new"
+    </screen>
+
