+libqrencode 3.4.4 - QR Code encoding library
+
+GENERAL INFORMATION
+===================
+Libqrencode is a library for encoding data in a QR Code symbol, a 2D symbology
+that can be scanned by handy terminals such as a mobile phone with CCD. The
+capacity of QR Code is up to 7000 digits or 4000 characters and has high
+robustness.
+
+Libqrencode accepts a string or a list of data chunks then encodes in a QR Code
+symbol as a bitmap array. While other QR Code applications generate an image
+file, using libqrencode allows applications to render QR Code symbols from raw
+bitmap data directly. This library also contains a command-line utility outputs
+a QR Code symbol as a PNG image.
+
+
+SPECIFICATION
+=============
+Libqrencode supports QR Code model 2, described in JIS (Japanese Industrial
+Standards) X0510:2004 or ISO/IEC 18004. Most of features in the specification
+are implemented such as:
+- Numeric, alphabet, Japanese kanji (Shift-JIS) or any 8 bit code can be
+  embedded
+- Optimized encoding of a string
+- Structured-append of symbols
+- Micro QR Code (experimental)
+
+Currently the following features are not supported:
+- ECI and FNC1 mode
+- QR Code model 1 (deprecated)
+
+
+INSTALL
+=======
+
+Requirements
+------------
+Some test programs or utility tools uses SDL or PNG, but the library itself
+has no dependencies. You can skip compiling those tools if you want not to
+install programs using SDL or PNG.
+
+Compile & install
+-----------------
+Just try
+
+./configure
+make
+make install
+
+This compiles and installs the library and header file to the appropriate
+directories. By default, /usr/local/lib and /usr/local/include. You can change
+the destination directory by passing some options to the configure script.
+Run "./configure --help" to see the list of options.
+
+It also installs a binary "qrencode" to /usr/local/bin. If you want not to
+install it, give "--without-tools" option to the configure script.
+
+When you downloaded a development tree from github, it is required to run
+"autogen.sh" at first to generate configure script.
+
+
+USAGE
+=====
+Basic usages of this library are written in the header file (qrencode.h).
+You can generate a manual of the library by using Doxygen.
+
+
+WARNINGS
+========
+The library is distributed WITHOUT ANY WRRANTY.
+
+Micro QR Code support is EXPERIMENTAL.
+
+Be careful to use the command line tool (qrencode) if it is used by a web
+application (e.g. CGI script). For example, giving "-s" option with a large
+number to qrencode may cause DoS. The parameters should be checked by the
+application.
