+# amalgamate.py - Amalgamate C source and header files
+
+Origin: https://bitbucket.org/erikedlund/amalgamate
+
+Mirror: https://github.com/edlund/amalgamate
+
+`amalgamate.py` aims to make it easy to use SQLite-style C source and header
+amalgamation in projects.
+
+For more information, please refer to: http://sqlite.org/amalgamation.html
+
+## Here be dragons
+
+`amalgamate.py` is quite dumb, it only knows the bare minimum about C code
+required in order to be able to handle trivial include directives. It can
+produce weird results for unexpected code.
+
+Things to be aware of:
+
+`amalgamate.py` will not handle complex include directives correctly:
+
+        #define HEADER_PATH "path/to/header.h"
+        #include HEADER_PATH
+
+In the above example, `path/to/header.h` will not be included in the
+amalgamation (HEADER_PATH is never expanded).
+
+`amalgamate.py` makes the assumption that each source and header file which
+is not empty will end in a new-line character, which is not immediately
+preceded by a backslash character (see 5.1.1.2p1.2 of ISO C99).
+
+`amalgamate.py` should be usable with C++ code, but raw string literals from
+C++11 will definitely cause problems:
+
+        R"delimiter(Terrible raw \ data " #include <sneaky.hpp>)delimiter"
+        R"delimiter(Terrible raw \ data " escaping)delimiter"
+
+In the examples above, `amalgamate.py` will stop parsing the raw string literal
+when it encounters the first quotation mark, which will produce unexpected
+results.
+
+## Installing amalgamate.py
+
+Python v.2.7.0 or higher is required.
+
+`amalgamate.py` can be tested and installed using the following commands:
+
+        ./test.sh && sudo -k cp ./amalgamate.py /usr/local/bin/
+
+## Using amalgamate.py
+
+        amalgamate.py [-v] -c path/to/config.json -s path/to/source/dir \
+                [-p path/to/prologue.(c|h)]
+
+ * The `-c, --config` option should specify the path to a JSON config file which
+   lists the source files, include paths and where to write the resulting
+   amalgamation. Have a look at `test/source.c.json` and `test/include.h.json`
+   to see two examples.
+
+ * The `-s, --source` option should specify the path to the source directory.
+   This is useful for supporting separate source and build directories.
+
+ * The `-p, --prologue` option should specify the path to a file which will be
+   added to the beginning of the amalgamation. It is optional.
