## Debug Tools
* cdm debug block
* CDM page debug mode: When CDM page debug mode enabled the start and end of cdm entity page creation is logged as well as any http request send via the cdm_api. The log is written to a file in the temporary folder configured in the File system settings. The log is written by the drupal devel module function dd(). r19752
