# Couple things of note here are the use of the `ios` tag and disabling CGO
# altogether.
#
# On our fork of go-ethereum, we've tagged `metrics/cpu.go` as so not to have
# it built on the `ios` and `android` targets via a build tag. This diverges
# from the upstream implementation, which does not have these tags.
#
# Metrics are captured through the use of a library, `gosigar`, which is an
# abstraction for capturing this sort of info across different operating
# systems. On Linux, for instance, it reads from the proc filesystem, but on
# Darwin/OSX it'll use syscalls that need C.
#
# Disabling CGO here is also necessary, as the tool doesn't play well with CGO
# at all. The tag and the environment variable are the combination that makes
# this work.
