+## autotools.mk
+
+This module defines configure, build and install targets by GNU autotools.
+These targets are implicit (e. g. `configure-%-stamp`), and you can completely
+override any of them by explicit target (e. g. `configure-foo-stamp`) in the top Makefile.
+Build and install targets use target-specific variable `target` for invoking `make`.
+This variable is empty for `build-%-stamp` and is set to "install" for `install-%-stamp`.
+You can redefine it in the top Makefile to build/install only a subset of a package. E. g.
+for NCurses with wide character support this will build and install only libraries (without
+programs and terminal database):
+
+ $(eval $(call add-variant,wide))
+ build-wide-stamp: target = libs
+ install-wide-stamp: target = install.libs
