# BENTOO-DIVERGENCE: metadata.xml - a <longdescription> saying why a prebuilt
# Blender exists beside the from-source one, an <upstream> block, and USE flag
# descriptions rewritten to state what the flags actually do here (they keep or
# drop vendor libraries already inside the tarball; they build nothing).
# ::gentoo's file carries none of the first two. Added documentation, not drift;
# there is nothing to align back to. The maintainer block differs for the usual
# definitional reason and is suppressed by the parity sweep on its own.
DESCRIPTION="3D Creation/Animation/Publishing System"
HOMEPAGE="https://www.blender.org"

# ver_cut rather than ${SLOT}, even though the two are the same string: it keeps
# SRC_URI free of any ordering dependency on SLOT, so the variables can stay in
# the canonical order pkgcheck expects.

LICENSE="GPL-3+ Apache-2.0"
# One slot per major.minor series.  .blend files are not forward compatible and
# addons routinely pin a series, so several Blender versions have to coexist.
SLOT="$(ver_cut 1-2)"
# Upstream publishes a single Linux build, linux-x64.  There is no arm64
# tarball in any release directory, so ~arm64 here would name a file that does
# not exist -- verified across the whole release index, not just this series.
