From b2bab951166ab30717b345b95b0dc8d6999ba16e Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Fri, 22 Jan 2021 10:48:51 +0100 Subject: [PATCH] maccalc: remove package This is a helpful utility, but it does not have any dependencies in this repository. Move it to packages feed. The package does not seem to have a maintainer.
