-- Changes:
-----------------------------------------------------------------------------
-- ToDo:
+-- -nohi doesn't work
-- new mkdependHS doesn't support all the options that the old one did (-X et al.)
-- time commands when run with -v
-- split marker
-- reading the package configuration file is too slow
-- -H, -K, -Rghc-timing
-- hi-diffs
+-- -ddump-all doesn't do anything
-----------------------------------------------------------------------------

-- make sure we clean up after ourselves
