# Golos.io Articles To CSV Converter
# This script works in 3 parts:
# 1. Loads user's articles from GOLOS.io.
# 2. Loads each articles statistics.
# 3. Converts statistics into one CSV file
# Save as like "articles.sh", do "chmod +x articles.sh", and then run script like this:
# ./articles.sh sxiii
# Replace sxiii with your GOLOS.io nickname
# Author: @sxiii
