+GNU make can utilize the Customs library, distributed with Pmake, to
+provide builds distributed across multiple hosts.
+
+In order to utilize this capability, you must first download and build
+the Customs library.  It is contained in the Pmake distribution, which
+can be obtained at:
+
+  ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/
+
+This integration was tested (superficially) with Pmake 2.1.33.
+
+
+BUILDING CUSTOMS
+----------------
+
+First, build pmake and Customs.  You need to build pmake first, because
+Customs require pmake to build.  Unfortunately, this is not trivial;
+please see the pmake and Customs documentation for details.  The best
+place to look for instructions is in the pmake-2.1.33/INSTALL file.
+
+Note that the 2.1.33 Pmake distribution comes with a set of patches to
+GNU make, distributed in the pmake-2.1.33/etc/gnumake/ directory.  These
+patches are based on GNU make 3.75 (there are patches for earlier
+versions of GNU make, also).  The parts of this patchfile which relate
+directly to Customs support have already been incorporated into this
+version of GNU make, so you should _NOT_ apply the patch file.
+
+However, there are a few non-Customs specific (as far as I could tell)
+changes here which are not incorporated (for example, the modification
+to try expanding -lfoo to libfoo.so).  If you rely on these changes
+you'll need to re-apply them by hand.
+
+Install the Customs library and header files according to the
+documentation.  You should also install the man pages (contrary to
+comments in the documentation, they weren't installed automatically for
+me; I had to cd to the ``pmake-2.1.33/doc'' directory and run ``pmake
+install'' there directly).
+
+
+BUILDING GNU MAKE
+-----------------
+
+Once you've installed Customs, you can build GNU make to use it.  When
+configuring GNU make, merely use the ``--with-customs=DIR'' option.
+Provide the directory containing the ``lib'' and ``include/customs''
+subdirectories as DIR.  For example, if you installed the customs
+library in /usr/local/lib and the headers in /usr/local/include/customs,
+then you'd pass ``--with-customs=/usr/local'' as an option to configure.
+
+Run make (or use build.sh) normally to build GNU make as described in
+the INSTALL file.
+
+See the documentation for Customs for information on starting and
+configuring Customs.
+
+
+PROBLEMS
+--------
+
+SunOS 4.1.x:
+  The customs/sprite.h header file #includes the <malloc.h> header
+  files; this conflicts with GNU make's configuration so you'll get a
+  compile error if you use GCC (or any other ANSI-capable C compiler).
+
+  I commented out the #include in sprite.h:107:
+
+    #if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi)
+    /* #include <malloc.h> */
+    #else
+
+  YMMV.
