The style000* directories in clientscript/vbulletin_css

[xyd]

I am using store CSS on the file system.

Does anyone know what the significance of these directories are:

They are located in /forum/clientscript/vbulletin_css/

style00007l
style00007r
style00008l
style00008r
style00009l
style00009r
style00010l
style00010r
style00011l
style00011r
style00012l
style00012r

I am writing a shell script to combine all of the css files into 1 (kind of like the rollup css files), but including every single css for each unique page.

However, I'm worried that one day vB will decide to switch the directory they save the css template changes to (which I make via the style editor in the admin CP).

Thanks for the help.
