-# checking that a file is haddocky:
-#   - checking if it has an export list
-#   - if there is no export list, it tries to find all defined functions
-#   - checking that all exported functions have type signatures
-#   - checking that the module header is OK
-
-# changes on files:
-#   - transforming hard space to ordinary space
-
-# limitations:
-#   - there might be some problems with nested comments
-#   - cannot handle type signatures for several functions
-#     (i.e. "a, b, c :: t")
-#     but on the other hand -- haddock has some problems with these too...
