 Package List and License

HARK includes dozens of packages with different licenses. The license basically depends on that of the original source code. For example, Julius related packages follow Julius license. Almost all packages are freely avalable with source codes, at least, for research purpose (non-commercial use).
Only an exception is asrasp-2.1.0 which is provided as binary without any source code (not open source).

We changed the structure of packages on Feb. 3, 2011. When you upgrade HARK, we strongly recommend that first remove all old packages and install new packages.
