This module polls various aspects of the host, to define the arch, os, etc. variables

val arch : OpamStateTypes.gt_variables -> string option

Functions to get host specification. It checks if variables value is defined in the environment map before polling.

val os : OpamStateTypes.gt_variables -> string option

val os_distribution : OpamStateTypes.gt_variables -> string option

val os_version : OpamStateTypes.gt_variables -> string option

val os_family : OpamStateTypes.gt_variables -> string option

val variables : 
  (OpamVariable.t * OpamTypes.variable_contents option Lazy.t) list

val normalise_arch : string -> string

The function used internally to get our canonical names for architectures (returns its input lowercased if not a recognised arch). This is typically called on the output of uname -m

val normalise_os : string -> string

The function used internally to get our canonical names for OSes (returns its input lowercased if not a recognised OS). This is typically called on the output of uname -s

val cores : unit -> int

val to_string : OpamStateTypes.gt_variables -> string

Returns a string containing arch, os, os-distribution & os-version values, unknown if they are not available. env is used to determine host specification.
