From 5d44df3af65767e731c0dd239bd1d9664edbb361 Mon Sep 17 00:00:00 2001 From: Profpatsch Date: Fri, 29 Jan 2021 15:39:33 +0100 Subject: refactor(users/Profpatsch): move arglib_netencode into its own lib arglib is the simple idea of passing structured data via a conventional environment variable instead of implementing an optparser for every little tool. Pop the envvar, decode the contents, return the contents.
