+                     imake and LCG-DM
+                     -----------------
+
+The LCG-DM software generation uses imake.
+This eases the port to new platforms, the customization for a specific
+project or site and an easy selection of a specific component.
+Furthermore the type of platform is normally selected without manual
+intervention.
+
+Implementation
+--------------
+
+Two directories have been added to the source structure: imake and
+config. The first one contains the source of the imake program which is part
+of the X11 distribution, the second one contains templates:
+
+   Imake.tmpl			does platform selection and includes
+	site.def		site selected defaults
+	'platform'.cf		platform specific template
+	Imake.rules		project specific rules
+   Library.tmpl			selects the list of libraries to put in 
+				the archive and shared global libraries.
+   Project.tmpl			selects the list of directories from
+				the site selected defaults.
+
+Setting the defaults
+--------------------
+
+Only the file site.def should be edited.
+It contains the pathnames for the configuration files, the logfiles
+and the directories where to install the commands, libraries and man pages.
+Be careful: put only one tab between variable name and value, otherwise cpp
+will crash on certain platforms.
+You specify there which components you want to be built:
+
+   BuildDPMClient		Disk Pool Manager Client api and utilities
+   BuildDPMServer		Disk Pool Manager daemon
+   BuildNameServerClient	Name Server Client api and utilities
+   BuildNameServerDaemon	Name Server daemon
+   BuildNameServerLibrary	Name Server API library
+   BuildNameServerAsLFC		LFC flavour of the Name Server (guid)
+   BuildNameServerAsDPNS	DPNS flavour of the Name Server (DPM Name Space)
+   BuildSRMv1Server		Storage Resource Manager v1
+   BuildSRMv2Server		Storage Resource Manager v2
+   BuildTest			LCG-DM test suite
+
+You specify there also special options like
+
+   HasNroff		to use the nroff program to format the man pages
+   UseMySQL		to use MySQL for the backend database
+   UseOracle		to use Oracle for the backend database
+
+
+
+Software build
+--------------
+
+When defaults are correctly set up in site.def, you may build the software.
+If you are on a Unix platform, you use:
+
+	make
+
+On Windows/NT, you should say:
+
+	make -f Makefile.ini.Win32
+
+(the program imake is automatically build if necessary).
+
+If you just want to create the makefiles without compiling,
+you should say at the top directory:
+
+	make Makefiles (under Unix)
+or
+	make -f Makefile.ini.Win32 Makefiles (under Windows/NT)
+
+Then you may simply type:
+
+	make (under Unix)
+or
+	nmake (under Windows/NT)
+
+in any subdirectory.
+
+If the Makefile at the top directory gets corrupted, you may restore
+a working version by typing:
+
+	cp Makefile.ini Makefile  (under Unix)
+or
+	cp Makefile.ini.Win32 Makefile (under Windows/NT)
+
+Then you can execute make as indicated above.
