Including this work alongside another work creates a collective work,
not a derivative work.  Such a collective work should include proper
attribution notices for its components, but the license requirements
do not extend to any other individual component comprising the
collective work.

Example 1: A web application that uses this software to manage its own
migrations.  If the application were distributed in a format that
includes this software, the distribution should include this work's
copyright notice.  The web application does not need to include such
notice, and does not fall under the license requirements of this work.
If the web application were also distributed without including this
work, that distribution would not need to include this work's
copyright notice.

Example 2: A web application that manages schema migrations, using
this software to do so.  This application is a derivative work, and
falls under every license requirement to that effect.
