if OpamProcess.is_success result then Done result.r_stdout
else failwith "ls"
val (@@+) : 'a job -> ('a -> 'b job) -> 'b job

job1 @@+ fun r -> job2 appends the computation of tasks in job2 after job1

val (@@|) : 'a job -> ('a -> 'b) -> 'b job

job @@| f maps f on the results of job. Equivalent to job @@+ fun r -> Done (f r)
