	 * dh_install: libmlpack-dev (4), libmlpack2 (2), mlpack-bin (2), mlpack-doc (28)
	If the missing files are installed by another tool, please file a bug against it.
	When filing the report, if the tool is not part of debhelper itself, please reference the

 Description: intuitive, fast, scalable C++ machine learning library (development libs)
  This package contains the mlpack Library development files.
  .
  Machine Learning Pack (mlpack) is an intuitive, fast, scalable C++
  machine learning library, meant to be a machine learning analog to
  LAPACK.  It aims to implement a wide array of machine learning
  methods and function as a "swiss army knife" for machine learning
  researchers.

 Description: intuitive, fast, scalable C++ machine learning library (runtime library)
  This package contains the mlpack Library runtime files.
  .
  Machine Learning Pack (mlpack) is an intuitive, fast, scalable C++
  machine learning library, meant to be a machine learning analog to
  LAPACK.  It aims to implement a wide array of machine learning
  methods and function as a "swiss army knife" for machine learning
  researchers.

 Description: intuitive, fast, scalable C++ machine learning library (binaries)
  This package contains example binaries using the mlpack Library.
  .
  Machine Learning Pack (mlpack) is an intuitive, fast, scalable C++
  machine learning library, meant to be a machine learning analog to
  LAPACK.  It aims to implement a wide array of machine learning
  methods and function as a "swiss army knife" for machine learning
  researchers.
