+ *   Are any of the dependencies missing or the wrong version?
+ *     If so, abort (unless --force-depends, in which case defer).
+ *   Will we need to configure a package we weren't given as an
+ *     argument? If so, abort ─ except if --force-configure-any,
+ *     in which case we add the package to the argument list.
+ *   If none of the above, defer the package.
+ *
+ * Try 2:
+ *   Find a cycle and break it (see above).
+ *   Do as for try 1.
+ *
+ * Try 3:
+ *   Start processing triggers if necessary.
+ *   Do as for try 2.
+ *
+ * Try 4:
+ *   Same as for try 3, but check trigger cycles even when deferring
+ *   processing due to unsatisfiable dependencies.
+ *
+ * Try 5 (only if --force-depends-version):
+ *   Same as for try 2, but don't mind version number in dependencies.
+ *
