+#   enumerate.sh
+#
+#   Enumerates all dependencies (imports) from Python modules in
+#   edx-platform.  The resulting data file generated at
+#   reports/dependencies/dependencies.txt can then be used by other scripts
+#   to detect inappropriate imports, such as:
+#
+#   * Imports of test modules or testing packages from core application code
+#   * Imports of development-only packages from core or test code
+#   * Imports from a package we want to stop using as a dependency
+#   * Imports of other edx-platform modules from a module we want to move to
+#     a separate package in its own repository
+#
+#   This script can take a while to run (a few minutes), so it should be run
+#   independently of the other scripts which use this data.
+#
+#   While running, a number of warnings such as "Could not import module
+#   'assert_equal'" may be generated.  This is normal; the snakefood utility
+#   can't really distinguish between the import of a module and the import of
+#   an object within a module, so it prints a warning on all instances of the
+#   latter just in case it actually was an attempt to import a module which
+#   it couldn't find in the current PYTHONPATH.  If you do see some modules
+#   listed which you think should be findable, you may need to run
+#   "make requirements" or update the ROOTS variable in this script.
