/**
* @file lib/package_configure.c
* @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.
