danbooru.py (http://untu.ms/danbooru/)
======================================
A content retrieval tool for danbooru (http://danbooru.donmai.us/). The
requirements are Python 2.5 (http://python.org/) and a little console-fu.
usage examples
==============
* danbooru.py negima "cat ears"
Download content tagged negima and cat_ears to the default folder
(negima+cat_ears)
* danbooru.py -x himm -r safe "sawatari izumi"
Download content tagged sawatari_izumi and rated safe (-r or --rating) to
a folder named himm (-f or --folder)
* danbooru.py -l 50 gif
Download content tagged as gif, limiting it to 50 posts (-l or --limit)
* danbooru.py -i -n -s 8 flash
Download content tagged flash, ignoring the youngest local file (or last
id, refers to the -i or --no-last-id option), ignore whether the file
exists in the local database (-n or --no-db), and use server 8 (-s or
--server option, use -L or --list to see a list of available servers)
* danbooru.py -c * -x *
Catalogue (-c or --catalogue) and rename (-x or --fix) all files in all
subfolders in the current path
* danbooru.py -h
View a list of available commands
version history
===============
* 0.3: 12.09.2007
* 0.2: 09.01.2007
* 0.1: 01.01.2007
