8 # @BLURB: support eclass for unpacking VCS snapshot tarballs
10 # This eclass provides a convenience src_unpack() which does unpack all
11 # the tarballs in SRC_URI to locations matching their (local) names,
12 # discarding the original parent directory.
14 # The typical use case are VCS snapshots, coming from github, bitbucket
15 # and similar services. They have hash appended to the directory name
16 # which makes extracting them a painful experience. But if you just use
17 # a SRC_URI arrow to rename it (which you're likely have to do anyway),
18 # vcs-snapshot will just extract it into a matching directory.
20 # Please note that this eclass handles only tarballs (.tar, .tar.gz,
21 # .tar.bz2 & .tar.xz). For any other file format (or suffix) it will
22 # fall back to regular unpack. Support for additional formats may be
23 # added at some point so please keep your SRC_URIs clean.
