Details:
I'd like to be able to write some rules like this:
file : %.tar
tar -xvf $<
file : %.tgz
tar -xzvf $<
file : %.tar.bzip2
tar -xjvf $<
etc., where the rules would be tested in sequence until one is found with
satisfiable pre-requisites. In this case it would look for any of the listed
tar-files and then apply the unpacking rule.
I know that there are ways around this, but the procedural solution of adding
conditional statements into the recipe body looks like a hack compared with
this.
Have you guys considered these kinds of OR-recipes for other reasons?
