	# Special Rules
	#
	# ObjectCCFlags              - C version of ObjectC++Flags
	# FRemoveAny x : y ;         - return new array of x minus any values in y
	# FRegexpQuote list ;        - quote regexp metacharacters into literals
	# FSplit s : delim ;         - split string at delim (default /)
	# FStringToList s ;          - return a list of chars from string
	# FLengthCmp s1 : s2 ;       - compare length of strings
	# FVersionCmp x : y ;        - compare version numbers (e.g. 3.4 vs. 4.5)
	# FDirEntries path : pat ;   - return a list of files matching pat in path
	# FileIsDir x ;              - returns just those elements that are existing directories
	# OnTargetVarPrepend TARGET  : VARIABLE : VALUES ;
	# OnTargetVarAppend  TARGET  : VARIABLE : VALUES ;
	# OnTargetVarDelete  TARGET  : VARIABLE : VALUES ;
	# LinkDir app : dir ;        - adds directory dir to the list of directories to be
	#                            - scanned for libraries
	# LinkLib app : lib ;        - adds library for an app
	# ExLibrary cpp ;            - same as Library, but with exception support
	# Deploy source : target ;   - copies the source into the target
    #                            - unlike InstallXYZ rules it ensures that directory will be created
    #                            - and the target will be forced to be created before the install
    #                            - operation is called
	# MakeLocateWithSubDirectory - same as MakeLocate but the targets may have sub directory
	#                              say object/depot.cpp

		# QtLupdate ts : h/s : files ; - Add sources/hdrs to lupdate

		# This rule is complicated, and here's why.
		#
		# TrollTech's lupdate command uses a .pro file to declare the name
		# and location of the .ts, source, and header files to be
		# processed.  Unfortunately, rather than computing the location of
		# these files relative to the current working directory, they are
		# determined relative to the location of the .pro file!
		#
		# The naive solution would be to write the .pro files out to the
		# current working directory, but that means parallel builds on
		# different platforms using a shared workspace can clobber each other.
		#
		# Writing the .pro files out to the build output directory is
		# pretty much impossible to do right, because Jam offers no way to
		# compute the relative path to a source file from any other
		# arbitrary location; you can only compute it from the current
		# working directory.  Thus, you might be able to finagle "jam
		# lupdate" to work from p4-bin, but then it would blow up if you
		# tried to run it from p4-qt.
		#
		# To avoid the platform-clobbering race, we create a temporary
		# directory in the current working directory, wherever that is,
		# write the .pro files there, and fix up the file paths using a
		# now-known relative prefix ("..") from cwd.  The .pro files are
		# then deleted and you wind up with an empty temporary directory.
		# There might be some clever way to remove that that I don't know
		# about, but it's a harmless artifact.
		#
		# If LUPDATE_MERGE is set, the .ts files are written to the
		# merged_lupdate.<platform> directory instead of the bin.<platform>
		# directory, and obsolete entries are retained.  These are the
		# versions of the files that should be checked back into
		# p4-qt/translations when they are to be permanently updated.
