[Solved] Clever-way of putting a md5sum after source in PKGBUILD?

Question

Been trying to find a way to do this.  'makepkg -g >> PKGBUILD' puts the md5sums at the end of the line and was hoping to find a way to put them after the source line.  Been thinking about a way to do this but it's pretty ugly.  Thinking something like this would do:
sed -e '1,/md5sum/d' PKGBUILD > PKGBUILD.tmp
sed -i '/md5sum/,/\t/d' PKGBUILD
makepkg -g PKGBUILD
cat PKGBUILD.tmp >> PKGBUILD
rm PKGBUILD.tmp
But thinking there's got to be a better way.  Has anyone come up (or have any ideas on how to) put md5sums after source?

I got a couple guys to help me out with this.  Awk it turns out is a much better way to do this.  Ah... awk.  Here's a more-awkward way of doing it:
awk 'BEGIN {
checkAt = 0
filesAt = 0
scanning = 0
/md5sums=\(/ {
checkAt = NR
scanning = 1
/source=\(/ {
filesAt = NR
scanning = 1
/)$/ {
if (scanning) {
if (checkAt > filesAt) {
checkEnd = NR
} else {
filesEnd = NR
scanning = 0
lines[NR] = $0
END {
for (i = 1; i <= NR; ++i) {
if (checkAt <= i && i <= checkEnd) {
continue
print lines[i]
if (i == filesEnd) {
for (j = checkAt; j <= checkEnd; ++j) {
print lines[j]
}' PKGBUILD > /tmp/PKGBUILD.tmp
mv /tmp/PKGBUILD.tmp PKGBUILD
This has the benefit of being able to put the md5sum after the source array even if it's before the source line.  Yah!
