+          These wide-character libraries are usable in both multibyte and

+          only in 8-bit locales. Wide-character and normal libraries are

+
+    <para>This package has a test suite, but it can only be run after the
+    package has been installed.  The tests reside in the
+    <filename class="directory">test/</filename> directory.  See the
+    <filename>README</filename> file in that directory for further details.

+
+    <para>Install the package:</para>
+
+<screen><userinput remap="install">make install</userinput></screen>
+
+    <para>Move the shared libraries to the
+    <filename class="directory">/lib</filename> directory, where they are
+    expected to reside:</para>
+
+<screen><userinput remap="install">mv -v /usr/lib/libncursesw.so.6* /lib</userinput></screen>
+
+    <para>Because the libraries have been moved, one symlink points to
+    a non-existent file. Recreate it:</para>
+
+<screen><userinput remap="install">ln -sfv ../../lib/$(readlink /usr/lib/libncursesw.so) /usr/lib/libncursesw.so</userinput></screen>
+
+    <para>Many applications still expect the linker to be able to find
+    non-wide-character Ncurses libraries. Trick such applications into linking with
+    wide-character libraries by means of symlinks and linker scripts:</para>
+
+<screen><userinput remap="install">for lib in ncurses form panel menu ; do
+    rm -vf                    /usr/lib/lib${lib}.so
+    echo "INPUT(-l${lib}w)" &gt; /usr/lib/lib${lib}.so
+    ln -sfv ${lib}w.pc        /usr/lib/pkgconfig/${lib}.pc
+done</userinput></screen>
+
+    <para>Finally, make sure that old applications that look for
+    <filename class="libraryfile">-lcurses</filename> at build time are still
+    buildable:</para>
+
+<screen><userinput remap="install">rm -vf                     /usr/lib/libcursesw.so
+echo "INPUT(-lncursesw)" &gt; /usr/lib/libcursesw.so
+ln -sfv libncurses.so      /usr/lib/libcurses.so</userinput></screen>
+
+    <para>If desired, install the Ncurses documentation:</para>
+
+<screen><userinput remap="install">mkdir -v       /usr/share/doc/ncurses-&ncurses-version;
+cp -v -R doc/* /usr/share/doc/ncurses-&ncurses-version;</userinput></screen>
+
+    <note>
+
+      <para>The instructions above don't create non-wide-character Ncurses
+      libraries since no package installed by compiling from sources would link
+      against them at runtime. However, the only known binary-only
+      applications that link against non-wide-character Ncurses libraries 
+      require version 5.  If you must have such libraries because of some binary-only
+      application or to be compliant with LSB, build the package again with the
+      following commands:</para>
+
+<screen role="nodump"><userinput>make distclean
+./configure --prefix=/usr    \
