	will set environment variable <VARIABLE>=<VALUE>

2012-12-11 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-14: Explicitly added -MF <file>.d in compilation command to let distcc
	properly deal with .d files.

2012-11-05 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-12/13: Now scram prints "gamke *** [ ] Error 1" type error message when it
	founds plugins/BuildFile.xml without any source files.

2012-10-25 Shahzad Muzaffar  <@smuzaffar>

	and CPPFLAGS as known compilers flags.

2012-09-14 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-06: Remove cms llvm checker category (it is not available)
	checker rule now dumps the build logs of individual products in to
	their build.log files.

2012-09-11 Giulio Eulisse <Giulio.Eulisse@cern.ch>

	* V04-02-05: Remove llvm-analysis/*/failures files

2012-07-16 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-04: By default enable all cms and threadsafety llvm checkers.

2012-06-28 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-03: By default do not run llvm-analyzer on generated e.g.
        xr.cc, LinkDef.cc etc. files. Set RUN_LLVM_ANALYZER_ON_ALL=yes
	if one needs to analyze generated code.

2012-06-21 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-02: Bug fix
	- Properly set ROOTCINT if not set via tool.
	- Properly generate lcg dict compiler generate source dependency.
	- Properly initialize compiler flags
	- Print warning if package directly depened on compiler tools except
	f77compiler.
	- Removed unused MODULEFLAGS, it is same as CXXSHAREDFLAGS.
	- Rules cleanup

2012-06-12 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-01: Replace hard coded value for llvm analyzer tool name.

2012-06-12 Shahzad Muzaffar  <@smuzaffar>

	* V04-02-00: 
	 - Allow multiple compilers support. Default compiler is gcc
	while one can run "scram b COMPILER=<name> to switch to a different
	compiler.
	 - Bug fix, if compilation failed then try to atleast generate compiler
	generate dependency file (.d) by using -MM flag.
	 - Drop headers for externals from the compiler generated dependency
	file.
	 - Support for llvm and llvm-analyzer compilers.
	 - Bug fix, while building patch release make sure that src/<package> for
	a python/<package> exists.

2012-05-23 Shahzad Muzaffar  <@smuzaffar>

	* V04-01-02: Do not recursively export an external tool if
	NO_RECURSIVE_EXPORT flag is set for it.

2012-05-07 Shahzad Muzaffar  <@smuzaffar>

	* V04-01-01: Auto generation of classes.h files
	- Added build rules for running genClassesH script of classes_def.xml
	exists but classes.h does not.
	- cleanup unused variables for LCGDict.
	- Enable autoGenerateClassesH for CMSSW
	- Delete product (lib.binary/test) before copy.

2012-04-26 Shahzad Muzaffar  <@smuzaffar>

	* V04-01-00:
	- Convert any LD_LIBRARY_PATH to DYLD_FALLBACK_LIBRARY_PATH on osx
	archs. This allows us to have osx* and slc* archs in single dev area,
	although it is unlikely that someone will do this but at least there
	is no restriction from SCRAM side now
	- Allow external scripts (hooks) to be called at Package/Product
	start/end time. One needs to have HOOK_PACKAGE/PRODUCT flag set in
	config/BuildFile.xml. SCRAM will call
	'$(HOOK_PACKAGE) -e|-s -p <Package|ProductName>' if HOOK_PACKAGE|PRODUCT
	is set.
	- Unit test dependency added e.g. 
	<bin file="Test2"><flags PRE_TEST="Test1"/></bin>
	will run Test1 first
	- For fortran file compilation/linking, automatically add f77_compiler
	dependency
	- Drop CMSSW LIBDIR which does not exist e.g. in dev area
	external/<arch>/lib does not exists (unless tool changed). This will
	avoid following kind of warnings on osx archs
	ld: warning: directory not found for option '-L<path>/external/<arch>/lib'
	- config/SCRAM/Plugins are now moved back to SCRAM itself.
