# Convienence class for extracting RPMs
# 
# Basically, rpm_src_unpack does:
#
# 1. convert all *.rpm in ${A} to tar.gz, non rpm files are passed through 
#    unpack()
# 2. unpacks the tar.gz into ${WORKDIR}
# 3. 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)
# 4. deletes all the unpacked tarballs and zip files from ${WORKDIR}
#
# Warning !!
#
# Sometimes, pure rpm2targz will fail on certain RPMs (eg: scim-chinese)
# because their code for detecting RPM header offset is not good enough.
# In that case, you need to add app-arch/rpm to your DEPEND. rpm2targz
# will automatically find rpm2cpio and use it instead of its own rpmoffset.
#
# Also, rpm2targz-8.0 behaves differently from rpm2targz-9.0. The newer
# versions will autodetect rpm2cpio whereas 8.0 doesn't. Also, 9.0 will
# detect if it is a source rpm and place files in ${prefix%.src} whereas
# 8.0 will just place them in the current directory. This eclass DEPENDS
# on rpm2targz 9.0.
