+ * Gettext 0.17 (or later).
+
+ * GNU M4 1.4.9 (or later).
+
+ * pkg-config 0.21 (or later).
+
+ * gperf 3.0.1 (or later).
+
+ * Gnulib, from Git at <git://git.savannah.gnu.org/gnulib.git>.
+ If you do not have Git installed, up-to-date snapshots are
+ at <http://git.savannah.gnu.org/gitweb/?p=gnulib.git>.
+ Note that Gnulib does not require any form of installation:
+ simply checking it out into a directory is sufficient. We
+ recommend checking out gnulib into a directory named `gnulib'
+ at the same level as PSPP.
+
+ * libtool 1.5.22 (or later).
+
+ * Texinfo 4.7 or later, to build the documentation.
+
+Once you have these installed, execute
+ make -f Smake
+If you checked Gnulib out in a directory named `gnulib' at the same
+level as PSPP, then this is sufficient. Otherwise, provide the
+location of GNULIB on the `make' command line:
+ make -f Smake GNULIB=/gnulib/base/directory/name
+
+After executing Smake, you may configure the source tree in the usual
+way with ./configure, e.g.
+ ./configure
+For a list of options:
+ ./configure --help
+
+To test:
+ make check
+
+For a very thorough test:
+ make distcheck
