+We want to ensure they all contain the appropriate license and copyright.
+
+For the purposes of this script, the *preamble* is defined as the first
+lines of the file starting with a hash (#).  Any line that does not start
+with a hash ends the preamble.
+
+Usage::
+
+    python check_preamble.py --replace /path/to/template.py script.py
+
+The above command reads the preamble from ``template.py``, and then copies
+that preamble into ``script.py``.  If ``script.py`` already contains a
+preamble, then the existing preamble will be replaced **entirely**.
+
+Processing entire subdirectories with one command::
+
+    find subdir1 subdir2 -iname "*.py" | xargs -n 1 python check_preamble.py --replace template.py
