create a git repository from a pile of tarballs (one tarball per commit, ordered cronologically, with the git dates forged to match the tarball dates)

pull.sh

#! /bin/ksh
#

extractomatic() {
    tarball=$1
    first_in_archive=`tar tzf $tarball | head -1`
    path=`dirname ${first_in_archive}/thing`
    when=`dateof $tarball`

    export GIT_COMMITTER_DATE="$when"
    export GIT_AUTHOR_DATE="$when"

    echo "extract $tarball to $path"
    tar xzf $tarball
    if [ "$path" != "." ]; then
	echo "rsync $path to ."
	rsync -ar $path/. .
	rm -rf $path
    fi
    echo -n "[more]"
    read me
}


for x in ` ls -1rt "$@" `;do
    messagetag=`basename $x`
    extractomatic "$x"
    for y in `git status -u | grep '#	'`; do
	if [ -f $y ]; then
	    case "`file $y`" in
	    *ELF*) rm $y ;;
	    esac
	fi
	if [ -f $y ]; then
	    case "$y" in
	    *.o)  rm $y ;;
	    *.gz) rm $y ;;
	    *)    git add $y ;;
	    esac
	fi
    done
    git commit -m "$messagetag" -a
    git tag "$messagetag"
done
