Several of our shell scripts hard-code the object ID of the empty tree. To avoid any problems when changing hashes, compute this value on startup of the script. For performance, store the value in a variable and reuse it throughout the life of the script.

This can cause problems if you want to work with people on other platforms.

To be portable it is advisable to rename the file.
