   1 # Run a builder, flip exit code, save log and fix outputs
   2 #
   3 # Sub-goals:
   4 # - Delegate to another original builder passed via args
   5 # - Save the build log to output for further checks
   6 # - Make the derivation succeed if the original builder fails
   7 # - Make the derivation fail if the original builder returns exit code 0
   8 #
   9 # Requirements:
  10 # This runs before, without and after stdenv. Do not modify the environment;
  11 # especially not before invoking the original builder. For example, use
  12 # "@" substitutions instead of PATH.
  13 # Do not export any variables.
