# We need the pppd source in order to build the PPP rp-pppoe plugin:
echo "Unpacking the pppd source"
# If working within /patches, we've done a hack for this - we copy the slackware64-current/source/n/ppp in to
# slackware64-14.2/patches/source
# This could be more elegant but it's not worth the effort presently.  This is just a note
# to remind me of WTF I did here later:

# Extract source:
tar xvvf $CWD/$PKGNAM-$VERSION.tar.!(*sign|*asc|*sig)
cd $PKGNAM-$VERSION || exit 1
