30 # - KBUILD_TARGET, KBUILD_HOST, KBUILD_HOST_ARCH, and KBUILD_TYPE in the env.
31 # - KBUILD_PATH points to ./kBuild with an absolute path.
32 # - KBUILD_BIN_PATH and PATH_KBUILD_BIN must *NOT* be defined anywhere.
33 # - Current directory == bootstrap.gmk directory.
37 # - cd somedir && command works.
38 # - echo done > some-file works.
39 # - Recent GNU make that implements CURDIR, $(error) and ifdef.
41 # Tip: kBuild/env.sh --full (g(nu))make -f bootstrap.kmk
47 # Set env.var. NIX_INSTALL_DIR to /usr/local or /usr
48 # (see Config.kmk and wiki for details)
52 # Deal with legacy env.vars. - no niceties here.
