This product provides a ZMI-manageable tool as a facade for the API exported by TrustCommerce's tclink Python library. Documentation and downloads for that library are available online:

In order to build the C extension which does the bulk of the work in the library, you need to have the openssl header files findable by your C compiler; you may need to install the libssl-dev or openssl-devel package to get these headers on some Linux distros.
