# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         docker
# Descr:       manager for applications in Linux containers
# URL:         https://www.docker.com/
# Build needs: go-md2man, google-go-lang >= 1.20
# Needs:       containerd, runc
# Changelog:   
# 20.10.12-1:  06/jan/2022 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
#                This package combines docker daemon, docker init, docker proxy,
#                docker commandline client, and the buildx plugin for the cli.
# 20.10.12-2:  07/jan/2022 by Eric Hameleers <alien@slackware.com>
#              * Added the man pages.
# 20.10.16-1:  19/may/2022 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 20.10.18-1:  12/oct/2022 by Eric Hameleers <alien@slackware.com>
#              * Update. Added docker-scan.
# 24.0.2-1:    03/jul/2023 by Eric Hameleers <alien@slackware.com>
#              * Update. Added docker-scan.
# 
# Run 'sh docker.SlackBuild' to build a Slackware package.
# The package (.t?z) and .txt file as well as build logs are created in /tmp .
# Install the package using 'installpkg' or 'upgradepkg --install-new'.
