7 # Convienence class for extracting RPMs
8 #
9 # Basically, rpm_src_unpack does:
10 #
11 # 1. uses rpm_unpack to unpack a rpm file using rpmoffset and cpio
12 # 2. if it is a source rpm, it finds all .tar .tar.gz, .tgz, .tbz2, .tar.bz2,
13 # .zip, .ZIP and unpacks them using unpack() (with a little hackery)
14 # 3. deletes all the unpacked tarballs and zip files from ${WORKDIR}
15 #
16 # This ebuild now re-defines a utility function called rpm_unpack which
17 # basically does what rpm2targz does, except faster. It does not gzip the
18 # output tar again but directly extracts to ${WORKDIR}
19 #
20 # It will autodetect for rpm2cpio (included in app-arch/rpm) and if it exists
21 # it will use that instead of the less reliable rpmoffset. This means if a
22 # particular rpm cannot be read using rpmoffset, you just need to put :
23 #
24 # DEPEND="app-arch/rpm"
25 #
26 # in your ebuild and it will install and use rpm2cpio instead. If you wish
27 # to force your ebuild to use rpmoffset in the presence of rpm2cpio, define:
