    <para><application>MC</application> (Midnight Commander) is a text-mode
    full-screen file manager and visual shell. It provides a clear,
    user-friendly, and somewhat protected interface to a Unix system while
    making many frequent file operations more efficient and preserving the
    full power of the command prompt.</para>

    <bridgehead renderas="sect3">Do I Need the Debian Patch?</bridgehead>
    <para>Midnight Commander without the Debian patch is completely unusable
    in multibyte locales because it assumes that characters and
    bytes are the same thing. The issue manifests itself as massive screen
    content corruption similar to what is depicted in
    <ulink url="&files-anduin;/mc-bad.png">this screenshot</ulink>
    (taken in the ru_RU.UTF-8 locale). For a general discussion of this type
    of issue, see the <xref linkend="locale-wrong-multibyte-characters"/>
    section of the <xref linkend="locale-issues"/> page. The Debian patch
    mostly fixes this issue, and adds support for recoding remote FTP
    filenames. Debian also fixed 64-bit issues, rare segfaults in
    <command>mcedit</command>, and improved syntax highlighting.</para>

    <para>If you do not use a multibyte locale and do not need any of the new
    features or fixes, the patch is still supposed to be harmless.
    However, the patch changes the dependencies and build instructions, and
    in the past it caused unacceptable regressions for non-UTF-8 locale users.
    Thus, failsafe instructions without the patch are left in the book just
    in case. Due to the size and unofficial nature of the patch, please
    do not report bugs in the patched <application>MC</application> to the
    original <application>MC</application> developers.</para>

    <title>Command Explanations</title>

    <para><parameter>CPPFLAGS="-DUTF8"</parameter>: This parameter activates
    UTF-8 support in the Debian patch and has no effect without this
    patch.</para>

    <para><parameter>--enable-charset</parameter>: This option adds support
    to <command>mcedit</command> for editing files in encodings different
    from the one implied by the current locale. This feature works in
    non-UTF-8 locales only, even with the Debian patch.</para>

    <para><parameter>--with-screen=(slang|mcslang|ncurses)</parameter>: This
    parameter selects the screen library used by <application>MC</application>.
    <application>NCurses</application> support is
    currently buggy (MC does not handle mouse events in xterm correctly).
    UTF-8 support in the Debian patch is functional
    only when external <xref linkend="slang"/> is used as a screen library
    (this is the default).</para>

    <para><parameter>--with-codepagedir=DIR</parameter>: This parameter was
    useful only with <application>SAMBA</application>-2.x. New versions of
    <application>SAMBA</application> do not have codepage files.</para>

    <para><command>chmod 1755 /usr/lib/mc/cons.saver</command>: The
    <command>cons.saver</command> program has to be installed setuid
    root, because on LFS regular users have no access to
    <filename>/dev/vcsa*</filename> devices. This step is optional if
    <application>MC</application> is going to be started from X terminal
    emulators or <command>ssh</command> sessions only (thus rendering the
    <command>cons.saver</command> binary completely unneeded).</para>

    <!-- Other distributions make the devices owned by the vcsa group
         and make the cons.saver program setgid vcsa instead -->
