+/**
+ * @file
+ * Invokes the Coder Upgrade conversion routines as a separate process.
+ *
+ * Using this script:
+ * - helps to minimize the memory usage by the web interface process
+ * - helps to avoid hitting memory and processing time limits by the PHP process
+ * - enables a batch processing workflow
+ *
+ * Parameters to this script:
+ * @param string $parameters
+ *   Path to a file containing runtime parameters
+ *
+ * The parameters should be stored as the serialized value of an associative
+ * array with the following keys:
+ * - paths: paths to files and modules
+ * - theme_cache: path to core theme information cache
+ * - variables: variables used by coder_upgrade
+ * - upgrades: array to be passed to coder_upgrade_start()
+ * - extensions: ditto
+ * - items: ditto
+ *
+ * @see coder_upgrade_conversions_prepare()
+ * @see coder_upgrade_parameters_save()
+ * @see coder_upgrade_start()
+ *
+ * To execute this script, run a command from the directory the standard output
+ * file is written to:
+ * - curl "http://dev.d7x.loc/coder_upgrade.run.php" > coder-upgrade-run.txt
+ *
