 This package provides a tool @exec{raco fmt} to reformat Racket code.
 
-The package uses @racketmodname[pretty-expressive], a very expressive pretty printer library, to compute the most optimal layout of the output code, and uses @racketmodname[syntax-color/module-lexer #:indirect] to lex the input program.

 The interface to allow users to extend formatting style is extremely unstable and is still a work in progress. For now, the only thing that is stable is the command @exec{raco fmt}.
