The syntax of a rule-line, though, is somewhat different, just as the meaning of targets is different. Targets for each file in your input tree there should be a target line. If you have no target nothing will be done.
Rules consist of keywords, labels and instructions.
This names the inputfile. The default is to take the target name and add .xml to it. The name of the output file. A file that should simply be copied. No processing of anything will be done it will simply be copied.
