 Only building the initial full source tree will be a bit painful.
 Later, a plain `git-pull && make' should be sufficient.
 
+* LZMA
+
+The coreutils build procedure can build distribution tarballs with the
+LZMA compression scheme.  This feature is so new that it is not
+supported by the latest version of Automake.  If you don't care about
+building LZMA tarballs, you can manually remove the string "dist-lzma"
+from configure.ac before bootstrapping.
+
+If you do want to build LZMA tarballs, you'll need to make sure you
+have the latest stable version of the LZMA SDK
+<http://www.7-zip.org/sdk.html>.  Also, you'll need a version of
+Automake that supports the dist-lzma feature, which was added to
+Automake on 2007-10-09 but is not yet available in a stable Automake
+version.  So until Automake 1.11 comes out, you'll need to get the
+bleeding-edge Automake version with a command like this:
+
+	$ cvs -d sources.redhat.com:/cvs/automake co automake
+	$ ./bootstrap
+	$ ./configure
+	$ make install
+
+and build and install that version.
