+Usage: ./configure [options]...
+
+This script configures notmuch to build on your system.
+
+It verifies that dependencies are available, determines flags needed
+to compile and link against various required libraries, and identifies
+whether various system functions can be used or if locally-provided
+replacements will be built instead.
+
+Finally, it allows you to control various aspects of the build and
+installation process.
+
+First, some common variables can specified via environment variables:
+
+	CC		The C compiler to use
+	CFLAGS		Flags to pass to the C compiler
+	CXX		The C++ compiler to use
+	CXXFLAGS	Flags to pass to the C compiler
+	LDFLAGS		Flags to pass when linking
+
+Each of these values can further be controlled by specifying them
+later on the "make" command line.
+
+Other environment variables can be used to control configure itself,
+(and for which there is no equivalent build-time control):
+
+	XAPIAN_CONFIG	The program to use to determine flags for
+			compiling and linking against the Xapian
+			library. [$XAPIAN_CONFIG]
+
+Additionally, various options can be specified on the configure
+command line.
+
+	--prefix=PREFIX	Install files in PREFIX [$PREFIX]
+
+By default, "make install" will install the resulting program to
+$PREFIX/bin, documentation to $PREFIX/man, etc. You can
+specify an installation prefix other than $PREFIX using
+--prefix, for instance:
+
+	./configure --prefix=\$HOME
+
+Fine tuning of some installation directories is available:
+
+	--libdir=DIR		Install libraries to DIR [PREFIX/lib]
+	--includedir=DIR	Install header files to DIR [PREFIX/include]
+	--mandir=DIR		Install man pages to DIR [PREFIX/share/man]
+	--sysconfdir=DIR	Read-only single-machine data [PREFIX/etc]
+	--emacslispdir=DIR	Elisp [PREFIX/share/emacs/site-lisp/notmuch]
+
+Additional options are accepted for compatibility with other
+configure-script calling conventions, but don't do anything yet:
+
+	--build=<cpu>-<vendor>-<os>	Currently ignored
+	--infodir=DIR			Currently ignored
+	--localstatedir=DIR		Currently ignored
+	--libexecdir=DIR		Currently ignored
+	--disable-maintainer-mode	Currently ignored
+	--disable-dependency-tracking	Currently ignored
