+# Convienence class for extracting RPMs
+#
+# Basically, rpm_src_unpack does:
+#
+# 1. uses rpm_unpack to unpack a rpm file using rpmoffset and cpio
+# 2. if it is a source rpm, it finds all .tar .tar.gz, .tgz, .tbz2, .tar.bz2,
+#    .zip, .ZIP and unpacks them using unpack() (with a little hackery)
+# 3. deletes all the unpacked tarballs and zip files from ${WORKDIR}
+#
+# This ebuild now re-defines a utility function called rpm_unpack which
+# basically does what rpm2targz does, except faster. It does not gzip the
+# output tar again but directly extracts to ${WORKDIR}
+#
+# It will autodetect for rpm2cpio (included in app-arch/rpm) and if it exists
+# it will use that instead of the less reliable rpmoffset. This means if a
+# particular rpm cannot be read using rpmoffset, you just need to put :
+#
+# DEPEND="app-arch/rpm"
+#
+# in your ebuild and it will install and use rpm2cpio instead. If you wish
+# to force your ebuild to use rpmoffset in the presence of rpm2cpio, define:
+#
+# USE_RPMOFFSET_ONLY="1"
+
+
+#USE_RPMOFFSET_ONLY=${USE_RPMOFFSET_ONLY-""}
+
+DEPEND=">=app-arch/rpm5offset-9.0"
+
+# extracts the contents of the RPM in ${WORKDIR}
