Re: pytagsfs image support


While there is no comment in code, I have difficulties to understand how the
code is organized and I would not spend much time doing reverse engineering
than coding.

1) Could you confirm that the metastores is the interface with file we would
And so, we can activate metastore with option "pytagsfs -o  metastores=..."

2) What is the purpose and how do you use "path.py" and  "testline.py"
metastore ?

3) Could you confirm that the "get" method is used to read keywords from
file given in path 

4) Could you confirm that the "set" method is used to write keywords within
file given by path

5) What is the type and organization of variable "values" in get and set :
list, tulp or dict ? 

6) Is there other method than "get" and "set" which must be programmed ?

7) How and where the format string is managed ? Are substitution sequence
also defined in metastore ?
