If there is a PKGBUILD in the cwd, and no package is specified, 'ccr-tools -s' should source the PKGBUILD, find the pkgver/pkgname/pkgrel, and if a source package exists, automatically choose that one to upload. This makes it possible to automate uploads of multiple packages, like

for pkg in `cat mypkglist`; do
    cd $pkg
    makepkg --source -f
    ccr-tools -s
    cd ..
done
