github_issues_to_csv_v3

require 'octokit'
require 'csv'

# Description:
# Exports Github issues from one or more repos into CSV file formatted for import into JIRA
# Note: By default, all Github comments will be assigned to the JIRA admin, appended with
# a note indicating the Github user who added the comment (since you may not have JIRA users
# created for all your Github users, especially if it is a public/open-source project:
#
#  Administrator added a comment - 13/Jun/12 5:13 PM
#  Imported from Github issue xyz-123, originally reported by ubercoder42
#
#  Administrator added a comment - 12/Jun/12 10:00 AM
#  Github comment from ubercoder42: [Text from first comment here...]

# Usage:
# > ruby github_issues_to_csv_v3.rb <JIRA admin username> <Github username> <Github password> <Github project/user> <repo 1> .. <repo n>
