  33 # usage: printdepends [brokenfile [bulkfilesdir]]
  34 #
  35 # Generates a list of package dependencies suitable for tsort(1) on
  36 # stdout. Each line of the output has two fields: the package directory
  37 # of the dependency and the package directory of the depending package
  38 # (both in the form category/package).
  39 #
  40 # If <brokenfile> is given, package-specific errors are logged to
  41 # <bulkfilesdir>/${pkgdir}/<brokenfile>. Otherwise no additional logging
  42 # takes place.
  43 #
  44 # The default for <bulkfilesdir> is the pkgsrc directory itself. If
  45 # <bulkfilesdir> differs from the pkgsrc directory, all directories
  46 # that are needed for the log files are created automatically.
  47 #
  48 # Note: printdepends must be called from a pkgsrc root directory.
