Attaching my current conceptual eclass. I've tested it with github, gitweb and bitbucket. It won't work with gitorious but their snapshot download mechanism is broken anyway (they like to submit 'try again later' in plaintext). -- Best regards, Michał Górny

# @BLURB: support eclass for VCS (github, bitbucket, gitweb) snapshots
# @DESCRIPTION:
# This eclass provides a convenience src_unpack() which does support
# working with snapshots generated by various VCS-es. It unpacks those
# to ${S} rather than the original directory containing commit id.
#
# Note that this eclass handles only unpacking. You need to specify
# SRC_URI yourself, and call any autoreconfiguration as necessary.
# The example does that using autotools-utils eclass.
#
# Right now, the eclass was tested with github, bitbucket and gitweb
# snapshots. Feel free to report snapshotting services which aren't
# working.
# @EXAMPLE:
#
# @CODE
# EAPI=4
# AUTOTOOLS_AUTORECONF=1
# inherit autotools-utils vcs-snapshot
#
# SRC_URI="http://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz"
# @CODE
case ${EAPI:-0} in
0|1) die "EAPI ${EAPI} unsupported.";; # default(), SRC_URI arrows
2|3|4) ;;
*) die "github-snapshot.eclass API in EAPI ${EAPI} not yet established."
