This approach is fine for rules within the ant rules. However, I'm using an
entity declaration and it doesn't take the variable value. However, this
approach is pretty good for other situations I have come across.

The build.template is placed relative to all my project directories. I
include this template into each project's build file and set only one
property (name).

My goal is to achieve three things with ant:
	1) Place virtually all the build rules in a template file
	2) Reuse this file for all projects and be able to set a couple of
variables to determine targets
	3) Construct a main build file which compiles all subprojects. 
This is a snap with makefiles but I am finding it really difficult to
achieve the above with ant. Ant is great for simple one build files (this
what got me hooked; especially the javac task). I really wish these
problems get resolve soon (I have to make a decision within the week on
whether to use this tool for the whole company).
