+/**
+ * Creates a machine name.
+ *
+ * The machine_name process plugin takes the source value and runs it through
+ * the transliteration service. This makes the source value lowercase,
+ * replaces anything that is not a number or a letter with an underscore,
+ * and removes duplicate underscores.
+ *
+ * Letters will have language decorations and accents removed.
+ *
+ * Example:
+ *
+ * @code
+ * process:
+ *   bar:
+ *     plugin: machine_name
+ *     source: foo
+ * @endcode
+ *
+ * If the value of foo in the source is 'áéí!' then the destination value of bar
+ * will be 'aei_'.
+ *
+ * @see \Drupal\migrate\Plugin\MigrateProcessInterface
+ *
+ * @MigrateProcessPlugin(
+ *   id = "machine_name"
+ * )
