;;; Build a user profile (essentially the union of all the installed packages)
;;; with its associated meta-data.

;;; Code:

(define* (build-profile output inputs
                        #:key manifest)
  "Build a user profile from INPUTS in directory OUTPUT.  Write MANIFEST, an
sexp, to OUTPUT/manifest."
  (union-build output inputs

  (call-with-output-file (string-append output "/manifest")
    (lambda (p)
      (pretty-print manifest p))))
