# Each directory to survive its way into a release will need a file

# in the tree will be processed, top down, in the following order.
|

|

# Hash started lines like this one are comments and will be deleted
|
||||
# before anything else is done. Blank lines will also be squashed
|

# out.
|

|

# The lines between the "Do-first:" line and the "Things-to-keep:"
|

# line are executed as a /bin/sh shell script before anything else is

# done in this directory.
