import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:

    pkg_resources.require("adodbapi")  # latest installed version
    pkg_resources.require("adodbapi==2.1")  # this exact version
    pkg_resources.require("adodbapi>=2.1")  # this version or higher
