# SWS installer script which does platform detection,

# downloads the corresponding pre-compiled binary and runs it.

# Usage:
|
|
# curl --proto '=https' --tlsv1.2 -sSfL https://get.static-web-server.net | sh
|

|

# Script adapted from https://github.com/rust-lang/rustup/blob/master/rustup-init.sh
|

# It runs on Unix shells like {a,ba,da,k,z}sh. It uses the common `local`
|
|
# extension. Note: Most shells limit `local` to 1 var per line, contra bash.
