Emscripten: Config and cache files should be stored in a special directory by default

[lormuc]

emscripten has already created these files in my home directory
.emscripten
.emscripten_cache__last_clear
.emscripten_ports/
.emscripten_sanity
.emscripten_cache/
.emscripten_cache.lock

To avoid cluttering ~, I suggest that such files be stored in something like ~/.emscripten.d/.

[kripken]

Sounds reasonable to me. Perhaps except for the .emscripten config file, though - moving that would be much more noticeable than the others, and could surprise people. But all the rest could be combined into one dir.

Pardon my intrusion. Why don't use XDG Base Directiry specification? I mean $XDG_CACHE_HOME, $XDG_CONFIG_HOME and $XDG_DATA_HOME which are ~/.config, ~/.cache and ~/.local/share, respectively, by default?
