+# The prerm script may be called in the following ways:
+#   * <postrm> 'remove'
+#   * <postrm> 'purge'
+#   * <old-postrm> 'upgrade' <new-version>
+#   * <disappearer's-postrm> 'disappear' <overwriter> <overwriter-version>
+#
+#     The postrm script is called after the package's files have been removed
+# or replaced. The package whose postrm is being called may have previously been
+# deconfigured and only be "Unpacked", at which point subsequent package changes
+# do not consider its dependencies. Therefore, all postrm actions may only rely
+# on essential packages and must gracefully skip any actions that require the
+# package's dependencies if those dependencies are unavailable.[48]
+#
+#   * <new-postrm> 'failed-upgrade' <old-version>
+#
+#     Called when the old postrm upgrade action fails. The new package will be
+# unpacked, but only essential packages and pre-dependencies can be relied on.
+# Pre-dependencies will either be configured or will be "Unpacked" or
+# "Half-Configured" but previously had been configured and was never removed.
+#
+#   * <new-postrm> 'abort-install'
+#   * <new-postrm> 'abort-install' <old-version>
+#   * <new-postrm> 'abort-upgrade' <old-version>
+#
+#     Called before unpacking the new package as part of the error handling of
+# preinst failures. May assume the same state as preinst can assume.
