* @file mintdb/perf_taler_mintdb_interpreter.h
* @brief Library for performance analysis of the Taler database
2015-06-09 17:35:33 +02:00
* @author Nicolas Fournier
2015-07-07 11:59:55 +02:00
*
* This library contains functions and macro alowing Taler performance analysis
* to be written with ease.
* To do so, create a #PERF_TALER_MINTDB_Cmd array and fill it with the commands
* to execute in chronological order. Some command have an exposed variable wich
* can be reused in other commands.
* Macros are available to make the use much easier so feel free to use them
* to initialize your own command array.
