 HOW TO BUILD -- UNIX
 
-Type `make'.
-
-This creates binaries "bzip2" and "bzip2recover".
-
-It also runs four compress-decompress tests to make sure things are
-working properly.  If all goes well, you should be up & running.
-Please be sure to read the output from `make' just to be sure that the
-tests went ok.
-
-To install bzip2 properly:
-
-* Copy the binaries "bzip2" and "bzip2recover" to a publically visible 
-  place, possibly /usr/bin or /usr/local/bin.
+Type `make'.  This builds the library libbz2.a and then the
+programs bzip2 and bzip2recover.  Six self-tests are run.
+If the self-tests complete ok, carry on to installation:
 
-* In that directory, make "bunzip2" and "bzcat" be symbolic links
-  to "bzip2".
+To install in /usr/bin, /usr/lib, /usr/man and /usr/include, type
+   make install
+To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type 
+   make install PREFIX=/xxx/yyy
+If you are (justifiably) paranoid and want to see what 'make install'
+is going to do, you can first do
+   make -n install                      or
+   make -n install PREFIX=/xxx/yyy      respectively.
+The -n instructs make to show the commands it would execute, but
+not actually execute them.
 
-* Copy the manual page, bzip2.1, to the relevant place.
-  Probably the right place is /usr/man/man1/.
-
-If you want to program with the library, you'll need to copy libbz2.a
-and bzlib.h to /usr/lib and /usr/include respectively.

 HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc.
 
 It's difficult for me to support compilation on all these platforms.
 My approach is to collect binaries for these platforms, and put them
-on my web page (http://www.muraroa.demon.co.uk).  Look there.
+on my web page (http://www.muraroa.demon.co.uk).  Look there.  However
+(FWIW), bzip2-0.9.5 is very standard ANSI C and should compile
+unmodified with MS Visual C.  For Win32, there is one important
+caveat: in bzip2.c, you must set BZ_UNIX to 0 and BZ_LCCWIN32 to 1
+before building.
