7     # Convienence class for extracting RPMs
8     #
9     # Basically, rpm_src_unpack does:
10     #
11 liquidx 1.5 # 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 liquidx 1.1 # .zip, .ZIP and unpacks them using unpack() (with a little hackery)
14 liquidx 1.5 # 3. deletes all the unpacked tarballs and zip files from ${WORKDIR}
15 liquidx 1.1 #
16 liquidx 1.5 # 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 liquidx 1.1 #
20 liquidx 1.5 # 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:
28     #
29     # USE_RPMOFFSET_ONLY="1"
