  Log:
  Somebody might want to combine literate programming with hsc
  preprocessing. This almost worked, but until now the preprocessor
  expected extension .hsc on input and always produced a file with
  extension .hs. So I am changing the extension game:
  
  Input file name should end with "c". The output will have the "c"
  removed. In particular Foo.hsc is transformed into Foo.hs and
  Foo.lhsc into Foo.lhs.
  
  When C wrappers are used inside, additional files are produced, with
  the final "c" changed into "c.h" and "c.c". E.g.
      Foo.hsc -> Foo.hs, Foo.hsc.h, Foo.hsc.c
  (previously they were Foo_hsc.{h,c}).
  
  Better suggestions are welcome. There is currently no -o option
  because up to three files may be produced and it is not clear how
  their names should be derived from one -o option.
  
  Some another preprocessor is free to use an analogous scheme, as long
  as it uses a different suffix than "c". Then it can be combined with
  hsc in any order, given appropriate Makefile rules.
