If you only need a single subdirectory with a custom prefix you could do
something like this (variables only used to keep the lines short):

	$ subdir=WebPortal/Templates
	$ prefix=myPath/myWeb/Templates/
	$ (cd "$subdir" && git archive --prefix="$prefix" HEAD) >my.tar

The output file can be specified with -o as well, of course, but you'd
either need to use an absolute path or add "../" for each directory
level you descend into (-o ../../my.tar in this case).
