bt_make and bt_wrap modules have been finally dropped in favour of the new bt_logic (a shell-based make-like utility). Several new checks have been added to bt_config. Support for a make-like '+=' operator has been added to bt_sh. Support for pkgconfig files and command line syntax has been added to bt_pkgflags. There have been several bugfixes. On the documentation side, a tutorial for developers has been added to the manual.
