+Build Instructions
+------------------
+
+* Requirements
+  ------------
+
+  - A Linux-based system with a standard C development environment
+  - GNU make version 3.81 or later
+  - skalibs version 2.5.1.1 or later: http://skarnet.org/software/skalibs/
+
+ This software is Linux-specific. It will run on a Linux kernel,
+version 2.6.32 or later. However, it is not hard to port to
+other Unix-like operating systems.
+
+
+* Standard usage
+  --------------
+
+  ./configure && make && sudo make install
+
+ will work for most users.
+ It will install the binaries in /usr/bin and the libraries in /usr/lib.
+
+ 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/)
+
+
+* 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.

+bcnm - a better client network manager
+--------------------------------------
+
+ bcnm is currently a set of tools to control the client side of a
+WiFi connection.
+
+ Ultimately, it aimes to become a network manager for client machines,
+similar to NetworkManager, wicd or ConnMan.
+ It works out-of-the-box on Linux and is easily portable to other
+Unix systems.
+
+ bcnm does not perform any low-level, hardware-controlling work itself.
+It just implements a state machine and send commands to other processes
+such as wpa_supplicant and a user-configured DHCP client.
+
+ See http://skarnet.org/software/bcnm/ for details.
+
+
+* Installation
+  ------------
+
+ See the INSTALL file.

+questions about bcnm.

+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]

+  --includedir=DIR              C header files [PREFIX/include]
+
+ If no --prefix option is given, by default libdir (but not dynlibdir) will be

+<h1> The <tt>wpactrl</tt> library interface </h1>
+
+<p>
+<tt>wpactrl</tt> is a library designed to interface a client
+with the <a href="https://w1.fi/wpa_supplicant/">wpa_supplicant</a>
+program, in a smaller, cleaner, more user-friendly and more
+packager-friendly way than the <tt>wpa_ctrl</tt> interface that
+comes with the <a href="https://w1.fi/wpa_supplicant/">wpa_supplicant</a>
+distribution.
+</p>
+
+<h2> Compiling </h2>
+
+<ul>
+ <li> Use <tt>#include &lt;bcnm/wpactrl.h&gt;</tt> </li>
+</ul>
+
+<h2> Linking </h2>
+
+<ul>
+ <li> Make sure the bcnm libraries, as well as the skalibs
+libraries, are visible in your library search path. </li>
+ <li> Link against <tt>-lwpactrl</tt> and <tt>-lskarnet</tt>.
+Also add <tt>`cat $sysdeps/socket.lib $sysdeps/tainnow.lib`</tt>
+to the end of your command line invoking the linker, in order
+to be portable to libcs that put socket or time functions into
+separate libraries.
+(<tt>$sysdeps</tt> stands for your skalibs sysdeps directory.) </li>
+</ul>
+
+
+<h2> Programming </h2>
+
+<p>
+ The <tt>bcnm/wpactrl.h</tt> header is the reference for the exact
+function prototypes.
+</p>
+
+<h3> General usage </h3>
+
+<p>
+ <tt>libwpactrl</tt> stores its information in a <tt>wpactrl_t</tt> structure.
+Such a structure must be allocated (can be declared in the stack) and
+initialized to WPACTRL_ZERO before use. The address of that <tt>wpactrl_t</tt>
+structure is then used as a handle and given as an argument to all the
+<tt>wpactrl_*</tt> function calls.
+</p>
+
+<h3> Connections </h3>
+
+<p>
+ A <tt>wpactrl_t</tt> instance represents two connections to a <tt>wpa_supplicant</tt>
+program: an <em>attached</em> one and a <em>detached</em> one. For proper operation,
+it is important to regularly read the data from the <em>attached</em> connection. This is
+achieved by calling the <tt>wpactrl_update()</tt> function whenever data is available
+on the <em>attached</em> connection; this is notified by the connection's fd becoming
+readable. The attached connection's fd can be obtained via the <tt>wpactrl_fd()</tt>
+function. So, proper usage of a <tt>wpactrl_t</tt> instance involves an asynchronous
+event loop.
+</p>
+
+<h3> Synchronous functions </h3>
+
+<p>
+ The bulk of <tt>libwpactrl</tt> functions take two extra arguments at the end, named
+<em>deadline</em> and <em>stamp</em>, of type
+<a href="//skarnet.org/software/skalibs/libstddjb/tai.html">tain_t</a>. This means
+they are synchronous function calls, and the extra arguments are there to ensure
+those calls do not block forever.
+</p>
+
+<p>
+<em>deadline</em> is an absolute date: if the function has not returned when this
+date is reached, it will immediately return with a code meaning "failure" and
+<tt>errno</tt> set to ETIMEDOUT. <em>stamp</em> must be first initialized to an
+accurate enough approximation of the current time, for instance via skalibs'
+<tt>tain_now()</tt> function; it will then be automatically updated by the
+libwpactrl function calls to always contain (an accurate enough approximation
+of) the current time.
+</p>
+
+<p>
+ <a href="//skarnet.org/software/skalibs/">skalibs</a> can keep track of the
+timestamp for you, in the global <tt>STAMP</tt> variable. All <tt>libwpactrl</tt>
+functions taking <em>deadline</em> and <em>stamp</em> arguments also have a
+version with a name ending in <tt>_g</tt>, that only takes a <tt>deadline</tt>
+argument, and assumes the <tt>STAMP</tt> variable always contains (an accurate
+enough approximation of) the current time.
+<p>
+
+<p>
+ Those synchronous function calls normally return almost instantly: there should
+be no blocking code path between the function call and its return. Nevertheless,
+since they involve communication with a complex <tt>wpa_supplicant</tt> process,
+it's impossible to guarantee that they will never block, so the deadline pattern
+is there to set a cap on the amount of time they block. A deadline set a few
+seconds into the future should be enough.
+</p>
+
+
+<h3> Starting and stopping a session </h3>
+
+<p>
+<code> int wpactrl_start (wpactrl_t *a, char const *path, tain_t const *deadline, tain_t *stamp) </code> <br />
+Starts a session with a <tt>wpa_supplicant</tt> instance listening on a Unix socket
+at <em>path</em>.
+The function returns 1 if it succeeds, or 0 (and sets errno) if
+it fails.
+</p>
+
+<p>
+<code> int wpactrl_end (wpactrl_t *a) </code> <br />
+Ends the session, freeing all used resources.
+</p>
+
+<h3> Low-level command sending </h3>
+
+<p>
+<code> ssize_t wpactrl_query (wpactrl_t *a, char const *q, size_t qlen, char *ans, size_t anslen, tain_t const *deadline, tain_t *stamp) </code> <br />
+Sends the query <em>q</em> of size <em>qlen</em> to the connected instance
+of wpa_supplicant, and reads its answer into the buffer pointed to by
+<em>ans</em>. Returns -1 in case of failure, or the number of bytes of
+the answer in case of success. Returns -1 with errno set to EMSGSIZE if
+the answer is bigger than <em>anslen</em> bytes.
+</p>
+
+<p>
+<code> ssize_t wpactrl_querysa (wpactrl_t *a, char const *q, size_t qlen, stralloc *sa, tain_t const *deadline, tain_t *stamp) </code> <br />
+Sends the query <em>q</em> of size <em>qlen</em> to the connected instance
+of wpa_supplicant, and reads its answer into the
+<a href="//skarnet.org/software/skalibs/libstddjb/stralloc.html">stralloc</a>
+pointed to by <em>sa</em>. Returns 1 if it succeeds and 0 if it fails.
+</p>
+
+<p>
+<code> wparesponse_t wpactrl_command (wpactrl_t *a, char const *q, size_t qlen, tain_t const *deadline, tain_t *stamp) </code> <br />
+Sends the command <em>q</em> of size <em>qlen</em> to the connected instance
+of wpa_supplicant, and returns its answer under the form of a
+<tt>wparesponse_t</tt>, which is an enumeration defined in the
+<tt>bcnm/wpactrl.h</tt> header. This function is meant to be used
+with commands returning a well-known value, such as <tt>RECONFIGURE</tt>
+(returning <tt>OK</tt> or <tt>FAIL</tt>) or <tt>PING</tt>
+(returning <tt>PONG</tt>).
+</p>
+
+<h3> Reading from the attached connection </h3>
+
+<p>
+<code> int wpactrl_update (wpactrl_t *a) </code> <br />
+Reads unsolicited messages from wpa_supplicant. If the messages
+are whitelisted, it keeps them, otherwise it discards them.
+The function returns the number of messages that have been read,
+or -1 in case of failure. A positive number does not mean that
+all pending messages have been read: there is a cap on the
+number of messages that can be consecutively read, to prevent
+a spamming wpa_supplicant from monopolizing your program.
+</p>
+
+<p>
+<code> char *wpactrl_data (wpactrl_t *a) </code> <br />
+Returns a pointer to the unsolicited messages from wpa_supplicant
+that have been read by <tt>wpactrl_update()</tt> but haven't been
+acknowledged yet.
+</p>
+
+<p>
+<code> char *wpactrl_datalen (wpactrl_t *a) </code> <br />
+Returns the length of unsolicited messages from wpa_supplicant
+that have been read by <tt>wpactrl_update()</tt> but haven't been
+acknowledged yet.
+</p>
+
+<p>
+<code> void wpactrl_ackdata (wpactrl_t *a) </code>
+Acknowledges reading the latest batch of unsolicited messages
+from wpa_supplicant: allows the next invocation of
+<tt>wpactrl_update()</tt> to reuse the storage.
+</p>
+
+<p>
+<code> int wpactrl_filter_add (wpactrl_t *a, char const *prefix) </code> <br />
+Adds <em>prefix</em> to the whitelist. Unsolicited messages from
+wpa_supplicant will be stored and made available to the application
+if they start with <tt>%lt;</tt><em>priority</em><tt>&gt;</tt><em>prefix</em>,
+<em>priority</em> being a single nonzero digit. If the filter is
+activated (which is the default), then only messages matching prefixes
+registered via <tt>wpactrl_filter_add()</tt> will be stored, and all
+other messages will be discarded. The function returns
+1 if it succeeds and 0 if it fails.
+</p>
+
+<p>
+<code> void wpactrl_filter_remove (wpactrl_t *a, char const *prefix) </code> <br />
+Removes <em>prefix</em> from the whitelist.
+</p>
+
+<p>
+<code> void wpactrl_filter_activate (wpactrl_t *a) </code>
+Activates the message filter. Unsolicited messages from
+wpa_supplicant will be discarded unless they are explicitly
+whitelisted by a call to <tt>wpactrl_filter_add()</tt>. This
+is the default.
+</p>
+
+<p>
+<code> void wpactrl_filter_deactivate (wpactrl_t *a) </code>
+Dectivates the message filter. All the unsolicited messages from
+wpa_supplicant will be stored and made available to the
+application.
