# How to use:
|
|
#
|
|
# 1. Before downloading any files
|
|
# orga = Organizer("/home/user/sync/", "/home/user/sync/bookstore/")
|
|
# orga.clean_temp_dir()
|
|
#
|
|
# 2. Downloading a file
|
|
# tempfile = orga.temp_file()
|
|
# download_something_to(tempfile)
|
|
# orga.add_file(tempfile, "books/douglas_adams/hhgttg"
|
|
#
|
|
# 3. After downloading all files
|
|
# orga.clean_sync_dir()
|
|
# orga.clean_temp_dir()
|
