+# THIS IS NOT A BUILDOUT FILE, despite purposedly using a compatible syntax.
+# The only allowed lines here are (regexes):
+# - "^#" comments, copied verbatim
+# - "^[" section beginings, copied verbatim
+# - lines containing an "=" sign which must fit in the following categorie.
+#   - "^\s*filename\s*=\s*path\s*$" where "path" is relative to this file
+#     Copied verbatim.
+#   - "^\s*hashtype\s*=.*" where "hashtype" is one of the values supported
+#     by the re-generation script.
+#     Re-generated.
+# - other lines are copied verbatim
+# Substitution (${...:...}), extension ([buildout] extends = ...) and
+# section inheritance (< = ...) are NOT supported (but you should really
+# not need these here).
