-OPEN SOLVER INTERFACE LIBRARY README
-=============================
-
-In this README,
-
-1. 'coin-Osi' is the full path to the directory in which you have 
-   dowloaded Osi.
-
-2. 'build' is the full path to the directory used for the installation 
-   of Osi. It might be coin-Osi or some other directory of your choosing.
-
-
-OVERVIEW
-========
-
-Welcome to the COIN-OR Open Solver Interface Library (Osi). Osi is
-distributed under the Eclipse Public License Version 1.0 and is freely
-redistributable. All source code and documentation is copyright by
-International Business Machines Corporation and (many) others.  This README
-file may be distributed freely.
-
-The COIN-OR Open Solver Interface Library is a collection of solver
-interfaces (SIs) that provide a common interface --- the OSI API --- for all
-the supported solvers.
-
-Each SI is in a separate directory. The authors of each SI are listed in the
-AUTHORS file in the subdirectory.  The names of maintainers and contributors
-to the base OsiSolverInterface code are listed in the AUTHORS file in this
-(Osi) directory.  For more information, see the Osi Trac page (see below).

-INSTALLATION
-============
-
-If you have downloaded the Osi package in the local directory coin-Osi,
-please see the INSTALL file in coin-Osi (the parent directory of this
-directory, unless you've changed the default Coin package directory
-structure) for instructions on how to install the entire package.
-
-If you have obtained Osi by downloading some other package, Osi will be 
-installed as part of the installation of that package. See the INSTALL 
-file in the main directory of the package (again, the parent directory of this
-directory).

-SUPPORT
-=======
-
-1. Authors
-
-   See the AUTHORS file.
-
-2. Project Managers
-
-   The main project managers are
-
-     Lou Hafer, [email protected]
-     Matt Saltzmann, [email protected]
-
-   Lots of others help out.
-
-3. Mailing List
-
-   Casual discussion of Osi can usually be found in the coin-discuss mailing
-   list. Serious discussion occurs in the coin-osi-devel mailing list. To
-   subscribe to either, go to http://list.coin-or.org/mailman/listinfo and
-   follow the links.
-
-4. Bug Reports
-
-   Bug reports should be reported by creating a ticket at
-   https://projects.coin-or.org/Osi/newticket
-
-   You will need to create a login id. We apologise for the hassle, but it's
-   the only way to avoid spammers. The more you can tell us about the bug
-   (version of Osi, compiler version, operating system, etc.) the better the
-   chance that we can duplicate your bug and fix it. It's helpful if you
-   leave a valid email address, in case we need to contact you for more
-   information.
-
-   You can also report bugs on the mailing lists, but you're at the mercy of
-   the memory of the developers. Once that email gets filed, well, out of
-   sight, out of mind.
-
-5. Requests for Enhancements
-
-   As for bugs, please create a ticket. Or, join the coin-osi-devel list and
-   lobby directly.
