DESCRIPTION="Amazon DCV remote display server (prebuilt binary)"
HOMEPAGE="https://aws.amazon.com/hpc/dcv/"

# Versioned distfile. AWS hosts per-release tarballs at
# https://d1uj6qtbmh3dt5.cloudfront.net/<release>/Servers/nice-dcv-<PV_DASH>-<elN>-x86_64.tgz
# where <PV_DASH> is the PV with the final dot replaced by a dash, and <elN>
# depends on the release era. We rename to ${P}.tgz so each ebuild has a
# unique, stable distfile name.
