"""

# Purpose: Get organizers and members for Team Drives

# Customize: DELIMITER, DOMAIN_LIST, INCLUDE_TYPES

# Python: Use python or python3 below as appropriate to your system; verify that you have version 3

# $ python -V or python3 -V

# Python 3.x.y

# Usage:

# 1: If you want to include all Team Drives, do this step and then skip to step 4, otherwise start at step 2.

# $ gam redirect csv ./TeamDrives.csv print teamdrives fields id,name

# 2: If you want Team Drives for a specific set of organizers, replace <UserTypeEntity> with your user selection in the command below

# $ gam redirect csv ./AllTeamDrives.csv <UserTypeEntity> print teamdrives fields id,name

# 3: Delete duplicate Team Drives (some may have multiple organizers). Make sure that ID_FIELD = 'id' in DeleteDuplicateRows.py

# $ python3 DeleteDuplicateRows.py ./AllTeamDrives.csv ./TeamDrives.csv

# 4: Get ACLs for all Team Drives

# $ gam redirect csv ./TeamDriveACLs.csv multiprocess csv ./TeamDrives.csv gam print drivefileacls "~id" fields id,emailaddress,role,type,deleted

# 5: From that list of ACLs, output a CSV file with headers "id,name,organizers,members"

# that shows the organizers for each Team Drive

# $ python3 GetTeamDriveMembers.py TeamDriveACLs.csv TeamDrives.csv TeamDriveMembers.csv
