Hi.

I've created a package which checks for the use of various js and css files. I'm matching the file path against:

DIR_REL . '/concrete/[css|js]/...'

That's worked fine up until now that somebody has deployed on a multisite solution. It appears the files are stored in:

/updates/100510/concrete/[css|js]/...

Could somebody explain this /updates/100510/ directory? When is it used? Is it always in the same format/name? What are the various constants (DIR_APP_UPDATES, DIRNAME_UPDATES, etc)?

Is there a constant that I can use, like:

SOME_CONSTANT . '/[css|js]'

which will either end up as:

/concrete/ (a normal install at the root)
/folder/concrete/ (when c5 doesn't sit at the root)
/updates/xxxxxx/concrete/ (multisite)
etc

It appears that I'll have to check for a few different scenarios manually...

Thanks,
James
