+Read this file first for a brief overview of the new versions of login
+and passwd.
+
+
+---Shadow passwords
+
+The command `shadowconfig on' will turn on shadow password support.
+`shadowconfig off' will turn it back off.  If you turn on shadow
+password support, you'll gain the ability to set password ages and
+expirations with chage(1).
+
+NOTE: If you use the nscd package, you may have problems with a
+slight delay in updating the password information. You may notice
+this during upgrades of certain packages that try to add a system
+user and then access the users information immediately afterwards.
+To avoid this, it is suggested that you stop the nscd daemon before
+upgrades, then restart it again.
+
+---General configuration
+
+Most of the configuration for the shadow utilities is in
+/etc/login.defs.  See login.defs(5).  The defaults are quite
+reasonable.
+
+Also see the /etc/pam.d/* files for each program to configure the PAM
+support. PAM documentation is available in several formats in the
+libpam-doc package.
+
+
+---MD5 Encryption
+
+This is enabled now using the /etc/pam.d/* files. Examples are given.
+
+
+---Adding users and groups
+
+Though you may add users and groups with the SysV type commands,
+useradd and groupadd, I recommend you add them with Debian adduser
+version 3+.  adduser gives you more configuration and conforms to the
+Debian UID and GID allocation.
+
+Editing user and group parameters can be done with usermod and
+groupmod.  Removing users and groups can be done with userdel and
+groupdel.
+
+
+--- Group administration
+
+Local group allocation is much easier.  With gpasswd(1) you can
+designate users to administer groups.  They can then securely add or
+remove users from the group.
+
+
+--- What to read next?
+
+Read the manpages, the other files in this directory, and the Shadow
+Password HOWTO (included in the doc-linux package).  A large portion
+of these files deals with getting shadow installed.  You can, of
+course, ignore those parts.
+
+Also, the libpam-doc package will go a long way to allowing you to take
+full advantage of the PAM authentication scheme.

+Things that should be done:
+ * Verify the files left in debian/tmp
+   + e.g. /etc/default/adduser should be installed
+ * Check the build system: rebuilding the package twoce in the same tree
+   doubles the size of the diff.gz file
+
+Other points (not related to the release of a syncronized shadow):
+ * compare the source with the usages and man pages
+   + probably add a sentence to chsh/chfn's manpages about authentication
+     required for ordinary users
+ * do something (a tool) for the variables in login.defs
+   In Debian, some tools are not compiled with the PAM support, so upstream
+   getdef.c won't be OK.
+   It should be nice to see in each man page the set of variables used.
+   The Debian package can now compile (export DEB_BUILD_OPTIONS='nostrip debug')
+   with the debugging informations. This may be used to extract the set of
+   variables used in Debian/for each tools.
+ * verify all the patches around (I've found patches for at least RedHat,
+   OWL, LFS, Mandriva, Gentoo; are they already applied?)

++.SH DESCRIPTION
++.PP
++\fBshadowconfig on\fP active les mots de passe cachés («\ shadow passwords\ »)\ ; \fBshadowconfig off\fP les désactive. \fBShadowconfig\fP affiche un message
++d'erreur et quitte avec une valeur de retour non nulle s'il rencontre
++quelque chose d'inattendu. Dans ce cas, vous devrez corriger l'erreur avant
++de recommencer.
++
++Activer les mots de passe cachés lorsqu'ils sont déjà activés, ou les
++désactiver lorsqu'ils ne sont pas actifs est sans effet.
++
++Lisez \fI/usr/share/doc/passwd/README.Debian\fP pour une brève introduction aux
++mots de passe cachés et à leurs fonctionnalités.
++
++Notez que désactiver puis réactiver les mots de passe cachés aura pour
++conséquence la perte des informations d'âge sur les mots de passe.

+Small intro to the system for numbering the patches here...
+
+-The 00xx-... patches are forwarded to upstream's git repository
+
+-The 0xx_... series of patches are patches isolated from the latest
+ version of the shadow Debian package not using quilt in order to
+ separate upstream from Debian-specific stuff.
+
+ NO MORE PATCHES SHOULD BE ADDED IN THESE SERIES
+
+-The 4xx series are patches which have been applied to Debian's shadow
+ and have NOT been accepted and/or applied upstream. These patches MUST be kept
+ even after resynced with upstream
+
+-The 5xx series are patches which are applied to Debian's shadow
+ and will never be proposed upstream because they're too specific
+ This list SHOULD BE AS SHORT AS POSSIBLE
+
+In short, while we are working towards synchronisation with upstream,
+our goal is to make 0xx patches disappear by moving them either to 3xx
+series (things already implemented upstream) or to 4xx series
+(Debian-specific patches).

+Date: Sun, 1 Dec 2019 13:59:52 -0800
+Subject: [PATCH] Revert "Honor --sbindir and --bindir for binary installation"
+
+This reverts commit e293aa9cfca0619a63616af75532637dab60d49d.
+
+See https://github.com/shadow-maint/shadow/issues/196
+
+Some distros still care about `/bin` vs `/usr/bin`. This commit makes
+it so all binaries are always installed to `/bin`/`/sbin`. The only way to
+restore the previous behaviour of installing some binaries to
+`/usr/bin`/`/usr/sbin` is to revert the patch.

+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
