+### Main functions
+* `bs_init()`
+* `bs_configure_packages(<package_rel_dir> [<used_package>...])`
 * `bs_generate_package(<pkg_name> [<dependency_target>...])`
+
+### Support functions
 * `bs_truncate_path(<root_path> <full_path>)`
-* `bs_copy_data(<relative_path>)`
 * `bs_set_pedantic_flags(<pkg_name>)`

 list(APPEND CMAKE_MODULE_PATH <CMAKE_CURRENT_LIST_DIR>/cmake)
 include(bs)
-bs_project(<project name>)
+bs_init()

+# packages in folder "packages"
+bs_configure_packages("packages" "${PACKAGE_NAMES}")
