/**
 * \file ograpispy.h
 *
 * OGR C API spy.
 *
 * If GDAL is compiled with OGRAPISPY_ENABLED defined (which is the case for a
 * DEBUG build), a mechanism to trace calls to the OGR *C* API is available
 * (calls to the C++ API will not be traced)
 *
 * Provided there is compile-time support, the mechanism must also be enabled at
 * runtime by setting the OGR_API_SPY_FILE configuration option
 * to a file where the calls to the OGR C API will be dumped (stdout and stderr
 * are recognized as special strings to name the standard output and error
 * files). The traced calls are outputted as a OGR Python script.
 *
 * Only calls that may have side-effects to the behavior of drivers are traced.
 *
 * If a file-based datasource is open in update mode, a snapshot of its initial
 * state is stored in a 'snapshot' directory, and then a copy of it is made as
 * the working datasource. That way, the generated script can be executed in a
 * reproducible way. The path for snapshots is the current working directory by
 * default, and can be changed by setting the OGR_API_SPY_SNAPSHOT_PATH
 * configuration option. If it is set to NO, the snapshot feature will be
 * disabled. The reliability of snapshoting relies on if the dataset correctly
 * implements GetFileList() (for multi-file datasources)
 *
 * @since GDAL 2.0
