+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]
+ --libdir=LIBDIR Install libraries in LIBDIR [$LIBDIR]
+
+By default, "make install" will install the resulting program to
+$PREFIX/bin, documentation to $PREFIX/share, etc. You can
+specify an installation prefix other than $PREFIX using
+--prefix, for instance:
+
+ ./configure --prefix=\$HOME
+
