[gentoo-dev] USE variables in SRC_URI

[Daniel Robbins <drobbins@gentoo.org>]

Hi devs,

I just added a new pre-release version of Portage to gentoo-src (developers
only) CVS that allows you to use USE variables in the SRC_URI as follows:

SRC_URI="foo? ( http://www.foo.bar/meep.tar.gz )"

We will gradually start using these features.  But right now I need testers.
If MAINTAINER is set to "yes", then all the USE variables in the SRC_URI will
default to "on", so that maintainers will be forced to test all SRC_URIs and
also cause complete digests to be generated.  You can also use the new "!foo?"
syntax in SRC_URIs and soon in DEPENDS and RDEPENDS as well.  This new version
of Portage also adds archive size to the digest files and uses a new file-based
DEPEND and RDEPEND passing method (for behind-the-scenes bash <-> python
integration.)

To test the new version of Portage, cvs update your gentoo-src module and copy
bin/ebuild.sh to /usr/lib/portage/bin, and pym/portage.py to
/usr/lib/portage/pym.

Best Regards,
