+      Usually you should only have one <code>@cImport</code> in your entire application, because it saves the compiler
+      from invoking clang multiple times, and prevents inline functions from being duplicated.

+      Reasons for having multiple <code>@cImport</code> expressions would be:

+      <ul>
+        <li>To avoid a symbol collision, for example if foo.h and bar.h both <code>#define CONNECTION_COUNT</code></li>
