# @BLURB: support eclass for unpacking VCS snapshot tarballs
# @DESCRIPTION:
# This eclass provides a convenience src_unpack() which does unpack all
# the tarballs in SRC_URI to locations matching their (local) names,
# discarding the original parent directory.
#
# The typical use case are VCS snapshots, coming from github, bitbucket
# and similar services. They have hash appended to the directory name
# which makes extracting them a painful experience. But if you just use
# a SRC_URI arrow to rename it (which you're likely have to do anyway),
# vcs-snapshot will just extract it into a matching directory.
#
# Please note that this eclass handles only tarballs (.tar, .tar.gz,
# .tar.bz2 & .tar.xz). For any other file format (or suffix) it will
# fall back to regular unpack. Support for additional formats may be
# added at some point so please keep your SRC_URIs clean.
#
# @EXAMPLE:
#
# @CODE
# EAPI=6
# inherit vcs-snapshot
#
# SRC_URI="https://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz
# https://github.com/example/${PN}-otherstuff/tarball/v${PV} -> ${P}-otherstuff.tar.gz""
# @CODE
#
# and however the tarballs were originally packed, all files will appear
# in ${WORKDIR}/${P} and ${WORKDIR}/${P}-otherstuff respectively.
