* @brief Package configuration routines
* @defgroup configure Package configuration functions
*
* Configure a package or all packages. Only packages in <b>unpacked</b>
* state will be processed (unless overriden). Package configuration steps:
*
* 1- Its <b>post-install</b> target in the INSTALL script will be executed.
*
* 2- Its state will be changed to <b>installed</b> if previous step
* ran successful.
*
* If the \a XBPS_FLAG_FORCE is set through xbps_set_flags(), the package
* (or packages) will be reconfigured even if its state is <b>installed</b>.
