 COMPILING

 You only need to download it, there is no need to compile.
 
 On most modern UNIX distributions, you can simply install 'boost' or
-'boost-dev' or 'boost-devel'. If you don't have that option, or don't want
-to use it, try:
-
-1) head to http://sourceforge.net/project/showfiles.php?group_id=7586 and
-download the latest boost tar.bz2 or tar.gz, perhaps from:
-http://downloads.sourceforge.net/project/boost/boost/1.39.0/boost_1_39_0.tar.bz2?use_mirror=ovh
-(use the first link if this one doesn't work)
-
-2) untar it:
-
-$ tar xjf boost_1_39_0.tar.bz2
-
-3) Compile the PowerDNS recursor using:
-
-$ CXXFLAGS=-I./boost_1_39_0/ ./configure
-$ CXXFLAGS=-I./boost_1_39_0/ make clean 
-$ CXXFLAGS=-I./boost_1_39_0/ make all
-(the 'clean' is needed to have make pick up the new boost)
-
-4) Run ./pdns_recursor and you should be set!
-
-5) (g)make install
-
-(use gmake on many BSD variant and Solaris, regular make on Linux)
+'boost-dev' or 'boost-devel'. Otherwise, just download boost, and point the
+compiler at the right directory using CPPFLAGS.
 
 OPTIONAL LUA SCRIPTING
 ----------------------
 To benefit from Lua scripting, as described on
 http://doc.powerdns.com/recursor-scripting.html please compile like this:
 
-$ LUA=1 (g)make
+$ LUA=1 ./configure ; LUA=1 (g)make
+
 or even
 
 $ LUA=1 LUA_CPPFLAGS_CONFIG=-I/usr/local/include/lua5.1 LUA_LIBS_CONFIG=-llua5.1\
+	./configure
+$ LUA=1 LUA_CPPFLAGS_CONFIG=-I/usr/local/include/lua5.1 LUA_LIBS_CONFIG=-llua5.1\
 	(g)make
 
 Use the _CONFIG settings to point out to PowerDNS where your Lua
-installation resides. PowerDNS supports both Lua 5.0 and 5.1.
-
-PLATFORM SPECIFIC NOTES
------------------------
-When compiling on Solaris 8, use:
-$ CPPFLAGS=-DSOLARIS8 ... gmake 
-
-where ... stands for any possible CXXFLAGS or PROFILEFLAGS, see below.
-
-PERFORMANCE
------------
-When on Intel/AMD, by ALL means use a 64-bit binary (not just a 64-bit
-kernel). This speeds up most things by at least a factor 2.
-
-For the utmost in performance, compile like this:
-
-   $ PROFILEFLAGS=-fprofile-generate make
-
-Then run the program for a bit, in as much of a real-life setting as you
-have available. Then run:
-
-   $ rec_control quit-nicely
-   bye nicely
-
-Then do:
-
-   $ PROFILEFLAGS=-fprofile-use make binclean all
-
-The resulting binary is up to 20% faster in our tests.
-
-Do run with g++ 4.4.1 if you can, it is the best.
