Documentation section 4.4.2 question/variant_isset

18 Dec 2007

      I don't think we should strongly recommend variant_isset usage in  
portfiles (in fact, I think we should recommend against it unless the  
alternative is extremely messy).

In the section 4.4.2 example, it seems much cleaner to do the following:

post-destroot {
	xinstall -m 755 -d ${destroot}${prefix}/etc/
	xinstall ${worksrcpath}/examples/foo.conf ${destroot}${prefix}/etc/
}
variant carbon {
	post-destroot {
		delete ${destroot}${prefix}/bin/emacs
		delete ${destroot}${prefix}/bin/emacs-${version}
	}
}
Since macports will run both post-destroot procs, the variant's code  
is then all contained within the variant.
