+lws and included programs are provided under the terms of the
+MIT license shown below, with the exception that some sources are under
+a similar permissive license like BSD, or are explicitly CC0 / public
+domain to remove any obstacles from basing differently-licensed code on
+them.
+
+Original liberal license retained:
+
+  - src/sha-1.c                        - 3-clause BSD license retained, link to original
+  - src/base64-decode.c                - already MIT
+
+Relicensed to MIT:
+
+  - src/daemonize.c                    - relicensed from Public Domain to MIT,
+                                         link to original Public Domain version
+  - lib/plat/windows/windows-resolv.c  - relicensed from "Beerware v42" to MIT
+
+Although lws is available under a permissive license, it does not
+change the reality of dealing with large lumps of external code... if your
+copy diverges it is guaranteed to contain security problems after a while
+and can be very painful to pick backports (especially since historically,
+we are very hot on cleaning and refactoring the codebase).  The least
+painful and lowest risk way remains sending your changes and fixes upstream
+to us so you can easily use later releases and fixes.

+lws is a small websocket library for embedded applications, and in particular, jsish.
+This is fork/refactor of Andy Green's https://github.com/warmcat/libwebsockets/tree/v2.2-stable
+If you need more a feature-full library, you should use libwebsockets instead.
+
+Goals of this refactor are:
+
+ - support only glibc/mingw/musl and openssl
+ - simplified application integration via lwsOne.c
+ - remove unused features
+ - fix bugs and memory leaks
+
+One line download/build:
+
+    wget http://jsish.org/fossil/lws/zip/lws?r=ver-2.0202 -O lws.zip && unzip -oq lws.zip && make -C lws
+
+For the latest release simply omit the ? query.
+
+Source is https://jsish.org/fossil/lws, but report bugs to mirror site: https://github.com/pcmacdon/lws
