/**

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