+Build Instructions
+------------------
+
+* Requirements
+ ------------
+
+ - A POSIX-compliant C development environment
+ - GNU make version 3.81 or later
+ - skalibs version 2.6.5.0 or later: http://skarnet.org/software/skalibs/
+
+ This software will run on any operating system that implements
+POSIX.1-2008, available at:
+ http://pubs.opengroup.org/onlinepubs/9699919799/
+
+
+* Standard usage
+ --------------
+
+ ./configure && make && sudo make install
+
+ will work for most users.
+ It will install the binaries in /bin and the static libraries in
+/usr/lib/nsss.
+
+ Please note that static libraries in /usr/lib/nsss *will not*
+be found by a default linker invocation: you need -L/usr/lib/nsss.
+Other skarnet.org software automatically handles that case if the
+default configuration is used, but if you change the configuration,
+remember to use the appropriate --with-lib configure option.
+
+ You can strip the binaries and libraries of their extra symbols via
+"make strip" before the "make install" phase. It will shave a few bytes
+off them.
+
+
+* Customization
+ -------------
+
+ You can customize paths via flags given to configure.
+ See ./configure --help for a list of all available configure options.
+
+
+* Environment variables
+ ---------------------
+
+ Controlling a build process via environment variables is a big and
+dangerous hammer. You should try and pass flags to configure instead;
+nevertheless, a few standard environment variables are recognized.
+
+ If the CC environment variable is set, its value will override compiler
+detection by configure. The --host=HOST option will still add a HOST-
+prefix to the value of CC.
+
+ The values of CFLAGS, CPPFLAGS and LDFLAGS will be appended to flags
+auto-detected by configure. To entirely override the flags set by
+configure instead, use make variables.
+
+
+* Make variables
+ --------------
+
+ You can invoke make with a few variables for more configuration.
+
+ CC, CFLAGS, CPPFLAGS, LDFLAGS, LDLIBS, AR, RANLIB, STRIP, INSTALL and
+CROSS_COMPILE can all be overridden on the make command line. This is
+an even bigger hammer than running ./configure with environment
+variables, so it is advised to only do this when it is the only way of
+obtaining the behaviour you want.
+
+ DESTDIR can be given on the "make install" command line in order to
+install to a staging directory.
+
+
+* Shared libraries
+ ----------------
+
+ Software from skarnet.org is small enough that shared libraries are
+generally not worth using. Static linking is simpler and incurs less
+runtime overhead and less points of failure: so by default, shared
+libraries are not built and binaries are linked against the static
+versions of the skarnet.org libraries. Nevertheless, you can:
+ * build shared libraries: --enable-shared
+ * link binaries against shared libraries: --disable-allstatic
+
+
+* Static binaries
+ ---------------
+
+ By default, binaries are linked against static versions of all the
+libraries they depend on, except for the libc. You can enforce
+linking against the static libc with --enable-static-libc.
+
+ (If you are using a GNU/Linux system, be aware that the GNU libc
+behaves badly with static linking and produces huge executables,
+which is why it is not the default. Other libcs are better suited
+to static linking, for instance musl: http://musl-libc.org/. If
+you're using nsss, chances are you're running musl, or a similar
+libc, anyway.)
+
+
+* Cross-compilation
+ -----------------
+
+ skarnet.org packages centralize all the difficulty of
+cross-compilation in one place: skalibs. Once you have
+cross-compiled skalibs, the rest is easy.
+
+ * Use the --host=HOST option to configure, HOST being the triplet
+for your target.
+ * Make sure your cross-toolchain binaries (i.e. prefixed with HOST-)
+are accessible via your PATH environment variable.
+ * Make sure to use the correct version of skalibs for your target,
+and the correct sysdeps directory, making use of the
+--with-include, --with-lib, --with-dynlib and --with-sysdeps
+options as necessary.
+
+
+* The slashpackage convention
+ ---------------------------
+
+ The slashpackage convention (http://cr.yp.to/slashpackage.html)
+is a package installation scheme that provides a few guarantees
+over other conventions such as the FHS, for instance fixed
+absolute pathnames. skarnet.org packages support it: use the
+--enable-slashpackage option to configure, or
+--enable-slashpackage=DIR for a prefixed DIR/package tree.
+This option will activate slashpackage support during the build
+and set slashpackage-compatible installation directories.
+If $package_home is the home of the package, defined as
+DIR/package/$category/$package-$version with the variables
+read from the package/info file, then:
+
+ --dynlibdir is set to $package_home/library.so
+ --bindir is set to $package_home/command
+ --sbindir is also set to $package_home/command (slashpackage
+differentiates root-only binaries by their Unix rights, not their
+location in the filesystem)
+ --libexecdir is also set to $package_home/command (slashpackage
+does not need a specific directory for internal binaries)
+ --libdir is set to $package_home/library
+ --includedir is set to $package_home/include
+
+ --prefix is pretty much ignored when you use --enable-slashpackage.
+You should probably not use both --enable-slashpackage and --prefix.
+
+ When using slashpackage, two additional Makefile targets are
+available after "make install":
+ - "make update" changes the default version of the software to the
+freshly installed one. (This is useful when you have several installed
+versions of the same software, which slashpackage supports.)
+ - "make -L global-links" adds links from /command and /library.so to the
+default version of the binaries and shared libraries. The "-L" option to
+make is necessary because targets are symbolic links, and the default make
+behaviour is to check the pointed file's timestamp and not the symlink's
+timestamp.
+
+
+* Absolute pathnames
+ ------------------
+
+ You may want to use fixed absolute pathnames even if you're not
+following the slashpackage convention: for instance, the Nix packaging
+system prefers calling binaries with immutable paths rather than rely on
+PATH resolution. If you are in that case, use the --enable-absolute-paths
+option to configure. This will ensure that programs calling binaries from
+this package will call them with their full installation path (in bindir)
+without relying on a PATH search.
+
+
+* Out-of-tree builds
+ ------------------
+
+ skarnet.org packages do not support out-of-tree builds. They
+are small, so it does not cost much to duplicate the entire
+source tree if parallel builds are needed.

+nsssd - a secure NSS-like implementation for small libcs
+--------------------------------------------------------
+
+ nsss is a library implementing a subset of pwd.h, group.h
+and shadow.h family of functions - the subset that can use a
+different backend than the standard /etc/passwd (et al.) files.
+It is intended to be used with certain libcs, such as musl, that
+do not implement the NSS protocol and so do not allow user/group
+credentials to be stored in other databases.
+
+ Unlike NSS, nsss does not load dynamic modules and is fully
+compatible with static linking. The backend is chosen at boot time
+by running the appropriate daemon that will communicate with
+clients.
+
+ See http://skarnet.org/software/nsss/ for details.
+
+
+* Installation
+ ------------
+
+ See the INSTALL file.
+
+
+* Contact information

+ This package assumes the existence of a POSIX shell in /bin/sh.
+ On Solaris, /bin/sh is not POSIX. Most versions of Solaris provide
+a POSIX shell in /usr/xpg4/bin/sh.
+
+ To compile this package on Solaris, you will need to run
+
+ ./patch-for-solaris
+
+ before you run ./configure. This script will change the #! invocation
+of the configure script and various tools so that a POSIX shell is used
+for the compilation process.

+Usage: $0 [OPTION]... [TARGET]
+
+Defaults for the options are specified in brackets.
+
+System types:
+ --target=TARGET configure to run on target TARGET [detected]
+ --host=TARGET same as --target
+
+Installation directories:
+ --prefix=PREFIX main installation prefix [/]
+ --exec-prefix=EPREFIX installation prefix for executable files [PREFIX]
+
+Fine tuning of the installation directories:
+ --dynlibdir=DIR shared library files [PREFIX/lib]
+ --bindir=BINDIR user executables [EPREFIX/bin]
+ --libexecdir=DIR package-scoped executables [EPREFIX/libexec]
+ --libdir=DIR static library files [PREFIX/lib/$package]
+ --includedir=DIR C header files [PREFIX/include]
+
+ If no --prefix option is given, by default libdir (but not dynlibdir) will be
+ /usr/lib/$package, and includedir will be /usr/include.
+
+Dependencies:
+ --with-sysdeps=DIR use sysdeps in DIR [PREFIX/lib/skalibs/sysdeps]
+ --with-include=DIR add DIR to the list of searched directories for headers
+ --with-lib=DIR add DIR to the list of searched directories for static libraries
+ --with-dynlib=DIR add DIR to the list of searched directories for shared libraries
+
+ If no --prefix option is given, by default sysdeps will be fetched from
+ /usr/lib/skalibs/sysdeps.
+
+Optional features:
+ --enable-shared build shared libraries [disabled]
+ --disable-static do not build static libraries [enabled]
+ --disable-allstatic do not prefer linking against static libraries [enabled]
+ --enable-static-libc make entirely static binaries [disabled]
+ --enable-all-pic build everything as PIC [enabled iff toolchain builds PIE]
+ --enable-slashpackage[=ROOT] assume /package installation at ROOT [disabled]
+ --enable-absolute-paths do not rely on PATH to access this package's binaries,
+ hardcode absolute BINDIR/foobar paths instead [disabled]
+
+ --with-nsssd-socket=PATH assume the nsssd socket is at PATH [/run/service/nsssd/s]

+<h1> nsss </h1>
+
+<h2> What is it&nbsp;? </h2>
+
+<p>
+ nsss is an implementation of a subset of the <tt>pwd.h</tt>,
+<tt>group.h</tt> and <tt>shadow.h</tt> family of functions,
+performing user database access on Unix systems.
+</p>
+
+<p>
+ Usually, user database access via <tt>getpwnam()</tt> and similar
+function is provided by the system's libc. However, not all libcs implement
+a configurable backend for the user/group database. For instance the
+<a href="https://musl-libc.org/">musl</a> libc, on Linux, only supports
+the standard <tt>/etc/passwd</tt> mechanism; it also supports the
+<tt>nscd</tt> protocol but this is not quite enough to implement the
+full set of database access functions with certain backends (such as a
+LDAP server).
+</p>
+
+<p>
+ <tt>nsss</tt> is a secure implementation of configurable user/group/shadow
+database access, providing <tt>getpwnam()</tt> et al. functionality
+by communicating over a Unix domain socket with a daemon; the daemon
+can perform lookups in any database it chooses.
+</p>
+
+<p>
+ Unlike NSS, <tt>nsss</tt> does not perform dynamic module
+loading, only adds a small footprint to the application's binary,
+and does not add any complex decision engine into the client's address
+space. Applications can be statically linked against the <tt>nsss</tt>
+library, and still benefit from configurable user database access
+functions.
+</p>

+
+<h1> The <tt>nsss</tt> library interface </h1>
+
+<h2> General information </h2>
+
+<p>
+ <tt>libnsss</tt> is a client library meant to be used by client
+programs needing utmp functionality. It interacts with various
+server-side daemons such as
+<a href="../nsssd-unix.html">nsssd-unix</a>.
+</p>
+
+<p>
+ Application programs can use it directly, but most existing programs
+simply use the standard
+<a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/pwd.h.html">pwd.h</a>,
+<a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/grp.h.html">grp.h</a> or
+<a href="http://man7.org/linux/man-pages/man3/getspnam.3.html">shadow.h</a>
+interfaces, which in nsss are implemented as a series of thin wrappers
+around the nsss library.
+</p>
+
+<h2> Compiling </h2>
+
+<ul>
+ <li> Make sure the nsss headers, as well as the skalibs headers,
+are visible in your header search path. </li>
+ <li> Use <tt>#include &lt;nsss/nsss.h&gt;</tt> </li>
+ <li> To use the standard <tt>pwd.h</tt> interface, you can
+just <tt>#include &lt;pwd.h&gt;</tt>, which will work as long
+as the <tt>nsss/pwd.h</tt> header is accessible in your header
+search path. </li>
+ <li> Same thing for <tt>grp.h</tt> and <tt>shadow.h</tt>. </li>
+</ul>
+
+<h2> Linking </h2>
+
+<ul>
+ <li> Make sure the nsss library, as well as the skalibs library,
+are visible in your library search path. </li>
+ <li> Link against <tt>-lnsss</tt>, <tt>-lskarnet</tt>, </li>
+<tt>`cat $SYSDEPS/socket.lib`</tt> and
+<tt>`cat $SYSDEPS/tainnow.lib`</tt>, $SYSDEPS being your skalibs
+sysdeps directory. </li>
+</ul>
+
+<h2> Programming </h2>
+
+<p>
+ The <tt>nsss/nsss.h</tt> header is actually a collection of headers:
+</p>
+
+<ul>
+ <li> <tt>nsss/nsss-unix.h</tt> implements basic access to the
+<tt>/etc/passwd</tt>, <tt>/etc/group</tt> and <tt>/etc/shadow</tt>
+database. </li>
+ <li> <tt>nsss/nsss-switch.h</tt> implements connection via a Unix
+domain socket to a listening <tt>nsssd</tt> daemon, implementing an
+authentication backend based on what implementation of
+the daemon is listening. </li>
+ <li> <tt>nsss/nsss-all.h</tt> implements a safe policy: first a
+connection via <tt>nsss-switch</tt> is attempted, and if no daemon
+is listening, the safe <tt>nsss-unix</tt> backend is used. </li>
+</ul>
+
+<p>
+ By default, the <tt>getpwnam()</tt> et al. functions are aliased
+to their <tt>nsss-all</tt> implementations. You can disable the
+<tt>nsss-unix</tt> fallback by compiling with the NSSS_DISABLE_UNIX
+macro defined (-DNSSS_DISABLE_UNIX). Or you can disable any
+attempt to connect to a daemon by compiling with the
+NSSS_DISABLE_SWITCH macro defined (-DNSSS_DISABLE_SWITCH).
