+transformers linked together with a command line frontend. The aim is to
+provide a tool that can be used to:
+
+- easily view the pre-processed version of a file, no need to construct a
complex command line: ppx file.ml will do
+- use a single executable to run several transformations: no need to fork many
times just for pre-processing
+- improved errors for misspelled/misplaced attributes and extension points.")
