Using XDG's user dir settings to determine where pictures are stored for a user (e.g., "~/Pictures" -- used as a fallback). May be overridden using "--exportdir". Also, while I was updating some docs, replace references to "Mac OS X" with "macOS", the new name of that OS these days.

/*
|
|
See tuxpaint.c for the OS-specific defaults.
|
|
|
|
* DIR_SAVE: Where does the user's drawings get saved?
|
|
|
|
This is where their saved files (PNG) are stored, and where the
|
|
"current_id.txt" file is saved (so we can re-load the latest
|
|
picture upon a subsequent launch). Generally, end users aren't
|
|
expected to access the files in here directly, but they can.
|
|
|
|
The defaults may be overridden with the "--savedir" option.
|
|
|
|
* DIR_DATA: Where is the user's data directory?
|
|
|
|
This is where local (user-specific) fonts, brushes, stamps,
|
|
starter images, etc., can be found. End users only put things
|
|
here if they wish to extend their Tux Paint experience.
|
|
|
|
The defaults may be overridden with the "--datadir" option.
|
|
|
|
* DIR_EXPORT: Where does Tux Paint export drawings / animations?
|
|
|
|
This is where single images, or animated GIF slideshows,
|
|
will be exported. It is expected that this is an obvious,
|
|
and easily-accessible place for end users to retrieve the exports.
|
|
|
|
The defaults may be overridden with the "--exportdir" option.
