The script below emulates these steps:
1) Use relative transcripts (you can convert them easily with sed if
you don't already have them)
2) Create a command file containing the loadset(s) you want and assign
it to your client
3) make a package_root directory on the client
4) cd to the package_root directory and use fsdiff/lapply to install
the loadset (you might need to do lapply -C unless you have all your
intermediate directories in the command file)
5) cd out of the package_root directory and do something like:

/Developer/usr/bin/packagemaker --id my.new.package --root
package_root --title"My Great Package" --target 10.4 --out
MyGreatPackage.pkg
