XDG

XDG Base Directory Standard

This provides a conveient library for conforming to the XDG Base Directory Standard.

Some important clarifications, not made clear by the above specification.

The data directories are for “read-only” files. In other words once something is put there, it should only be read, never written to by a program. (Generally speaking only users or pacakge mangers should be adding, changing or removing files from the data locations.

The config locations are where you should store files that may change, and effect operations depending one there content. This is like etc/ in the FHS, but alterable by end users and and end user programs, not just root and sudo admin scripts.

The cache location stores files that could judt as well be deleted and everyihtng still works find. This is for variable and temporary files. Like var/ in FHS.

This module returns paths as strings.
