systems including various flavors of Linux; Darwin; and Cygwin (has not been
tested on more "exotic" varieties of UNIX). For Windows installation
instructions (excluding Cygwin), see windows/INSTALL.

Development pattern for contributors
- Create a personal fork of the main Kaldi repository in GitHub.
- Make your changes in a named branch different from
master, e.g. you create a branchmy-awesome-feature. - Generate a pull request through the Web interface of GitHub.
- As a general rule, please follow Google C++ Style Guide. There are a few exceptions in Kaldi. You can use the Google's cpplint.py to verify that your code is free of basic mistakes.
