Interpret the sed command.

Could you interpret the following sed and awk command for me?

command:
cat tempfile2 |sed "s/\(BUILD-3-.*-[0-9]\.[0-9]-\)\([0-9].*\.[0-9].*\.[0-9].*\)/\2/" | awk '{printf "%-8.8s %-23.23s %-30.30s %-50.50s\n", $1,$2,$3,substr($0,index($0,$4))}' > outfile2 2>/dev/null

inputSmiliedata in tempfile2)
BUILD-3-CbsOrderDTVInterfaceV2-1.0-2.0.7 DCR-14447 vk0957-?Vikas?Kaward validate?BTN?field?as?alphnumeric?instead?of?numeric.
