1. Download the file for the appropriate operating system (<OS>).
2. In order to unzip the downloaded file, use the command gunzip wsmp-<OS>.tar.gz.
3. In order to extract the wsmp-<OS>/ directory and its contents, use the command tar -xvf wsmp-<OS>.tar.
4. Please refer to the README file in this directory for further instructions.

Details on linking and running with the libraries can be found in the doc/wsmp1.pdf (symmetric solver) and doc/wsmp2.pdf (general solver) files.

In brief, the software is available in the form of statically linkable libraries. The documentation describes the calling sequences and other details of the computational routines. The users need to place calls to the appropriate WSMP routines in their code and link it with the WSMP libraries to create an executable.
