pfserver helps you download from rapidshare. It's intend to be used as server, but since it's modular, you could write a downloader by using the pfmanager module

important: first you should create a cfg folder, than you need to create a userconfig file and define some constants: NAME= #project name, main file to execute without .py INCLUDE= files which should be included in packet ARGS= arguments which should be passed to main-file

typical config file looks like this:
from /full/path/to/dir-where-to-save-the-rar-files
to /full/path/to/dir-where-to-extract-the-rar-files
pwd possible-passwords
cfg /full/path/to/config-directory
