type Ketrew_pure.Host.t
val default_timeout_upper_bound : float Pervasives.ref
Default (upper bound) of the `?timeout` arguments.
type [ `At_most_seconds of float | `Host_default | `None | `Seconds of float ]
Timeout specification for execution functions below.
`Host_default → use the excution_timeout value of the host. `None → force no timeout even if the host has a execution_timeout.`Seconds f → use f seconds as timeout.`At_most_seconds f -> use f seconds, unless the host has a smaller
execution_timeout field.
The default value is
`At_most_seconds !default_timeout_upper_bound.

Unix_io.Deferred_result.t
Generic execution which tries to behave like Unix.execv even
on top of SSH.
type string -> string list
A “shell” is a function that takes a command and returns, and
execv-style string list; the default for each host
is "sh"; "-c"; cmd
val shell_sh : sh:string -> shell
Call sh-style commands using the command argument (e.g. shell_sh "/bin/sh"
for a known path or command).
