+ * @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 is set through xbps_set_flags(), the package
+ * (or packages) will be reconfigured even if its state is
+ * XBPS_PKG_STATE_INSTALLED.
