[Pythonmac-SIG] Shelve ... Denied!

[Israel C. Evans]

Hey there.. Thanks for this bit of help..
permissions and chmod still twist my brain for some odd reason, but I 
think I do have this working.

The problem I'm having is that I need to be able to create new shelve 
db's through this web interface I'm building here.  I'm confused as to 
how I should go about setting the permissions for various users so that 
they can create, edit, save and delete files based upon their 
permissions.

Are there any tutorials or articles any of you have found particularly 
helpful in regards to this subject? Or, better yet, would any of you 
have a little knowledge pill handy that could magically endow me with 
the know how to do this?  No?  oh well.  I'll just have to do it the 
hard way...
Now in regards to articles or other help, I would be most grateful for 
said objects of desire.

Thanks much,

~Israel~
