+asdcplib
+======
+
+This branch is based on asdcplib 2.5.11 and has the following basic changes needed for [libdcp](https://github.com/cth103/libdcp) and hence [DCP-o-matic](https://github.com/cth103/dcpomatic):
+
+- Tweaks to allow resumption of writes to partial MXFs.
+- Additions to allow hashing of MXFs while they are being written.
+- Replacement of some code with shorter versions using boost.
+- Fixes for various compiler warnings.
+
+asdcplib is ‘an open source implementation of SMPTE and the MXF Interop “Sound & Picture Track File” format. It was originally developed with support from DCI. Development is currently supported by CineCert and other d-cinema manufacturers. See the bundled README file for more information. asdcplib is implemented in C++ and builds on Win32 and most unix platforms that support GCC.’
