Subject: Initial public commit.

mDNS and SDP are functional. Otherwise, library is still very much
a work in progress. All tests pass.

+liburtc
+=======
+
+Real-time communication for microcontrollers
+
+The WebRTC reference implementation was designed for web browsers, namely
+Chromium. It requires specialized build tools, over 10GB of disk space for
+source code, and produces a binary with a large footprint. liburtc, on the
+other hand, is designed with the following goals in mind:
+
+* Small footprint. Under 100KB.
+* Portable. Implemented in C (C99) and works on nearly any architecture and
+  POSIX.1-2001 compliant operating system.
+* Easy to use. Straight-forward to compile and integrate into your code.
+* Standards compliant. Adheres to IETF specs to ensure interoperability.
+* Minimal. Only implements subset of protocols required for basic functionality
+  for common embedded applications, such as smart cameras.
+* Minimal dependencies. Only dependency is OpenSSL.
+
+
+Bootstrapping
+-------------
+
+If checking out this code via `git`, run `autoconf` to generate a `configure`
+script.
+
+
+Quickstart
+----------
+
+To compile the library and usage example from source, you will need autoconf,
+automake, and libtool. Use `autogen.sh` to create a `configure` script for
+configuring and making the library:
+
+    ./autogen.sh && ./configure && make
+
+To test the library:
+
+    make check
+
+Next, see `example/README.md` for running a demo.
+
+
+Features

+
+- Video codecs:
+  - H.264
+    - Profiles: baseline, constrained baseline, main, high
+    - Levels: 3.1 and up
+  - H.265 not supported (few, if any, browsers support this)
+  - VP8/9 not supported (few embedded devices support this)

+
+- Diego Elio Petteno (https://autotools.io) for the wonderful resource on
+  autoconf, automake, libtool, and other tools in the autotools suite.
