# Usage
#
# 1. Save this code as `export_rebloggers.py` in your computer;
#
# 2. Edit it, note that there are three places need to be changed:
#
#   a. <your_access_token_here> (line 30)
#           You can get your access token by: Settings -> Development ->
#       NEW APPLICATION -> fill in an application name -> SUBMIT -> click your
#       application name -> you will see your access token.
#
#   b. <mastodon.example> (line 31)
#           Replace it with the domain address of the instance you are using.
#
#   c. <:id> (line 32)
#           The id of the toot whose rebloggers you want to collect.
#
# 3. Execute this python file, and deal with the output as you like. For example,
#       in Linux, you can `export_rebloggers.py > rebloggers_list`.
