			Tag File System

			

Copyright: never think about that.

Bugfix:

	When creating new file, '/' will be a tag in file.

	TagDB.add_file_tags can not deal with [] tags.

	

	Readdir support sub-tags. So that 'ls' can list directories.

Install:

	This filesystem requires the followings:

		Python 2.6

		FUSE-2 library

		Python-fuse library

		Python xattr package if you want to use lstags.py command

		Better in a Linux box

	Python version < 2.6 is not supported.

	Python 3000 is not tested yet. If you insist, try convert the 2.6 code 

	to 3.0.

	

To Mount:

	Firstly some issues:

	Tagfs needs a back-store directory to save its meta data and the actual

	files. Operations under the mounting point directory are actually 

	translated into tagfs actions and performed in the files under back-store

	directory.

	

	It is better that the back-store directory is empty and if some errors 

	occur, remove the .tagfs_db.meta file in the back-store.

	

	For most file operations, tagfs just mirror the underlying filesystem

	APIs. The chief difference is the path-lookup which is based on tag query

	in tagfs. Each directory in a path is considered to be a tag, the order

	is irrelevant. So 'utah/picture/by-me/' refers to files with tags: picture,

	utah and by-me.

	

	Now the steps:	

	Download the sources from GoogleCode trunk.

	In the up-most dir which contains cmd and tagfs sub-dirs, 

	run: ./tagfs/TagFS.py -o root= 

	

	The tagfs will use  to store the meta data and 

	files. You can do things within  to have fun.

	If you want to monitor the status, use -d option when running TagFs.py

	to enable debug output.

	The log is in /tmp/tagfs.log 

	

Command:

	cmd/lstags.py:

		lstags.py 

		if  is a file: list all tags of that file, in a path format

		if  is a dir(or we say 'tags' in tagfs): list the union of all 

			of all tags that are attached by files under , but the 

			tags in  path are not listed. So it looks like 'sub-tags' 

			under , however, in fact there is not hierarchy relationship 

			between tags.

		

		For convenience, you may want to add the dir containing lstags.py to PATH.
