# Title: COPR Mirror Script
# Project: coprmirror
# Purpose: Mirror all available architectures of a COPR to local disk
# History:
# Usage:
#    In a cronjob:
#    COPRMIRROR_CONF=coprmirror.conf ./coprmirror.sh 1>/dev/null 2>&1
# Reference:
#    yummirror.sh
# Improve:
# Dependencies:
#    yummirror.sh from this project

# Flow: given a copr name, find all release-releasever-basearch entries, and pass each one to coprmirror-single.sh
