"""
|
|
This class deals with getting, storing and serving up artwork (album art,
|
|
artist images, etc) and info/descriptions (album info, artist descrptions)
|
|
to and from the cache folder. This can be called from within a web
|
|
interface. For example, using the helper functions `getInfo(id)` and
|
|
`getArtwork(id)`, to utilize the cached images rather than having to
|
|
retrieve them every time the page is reloaded.
|
|
|
|
You can call `getArtwork(id)` which will return an absolute path to the
|
|
image file on the local machine, or if the cache directory doesn't exist,
|
|
or can not be written to, it will return a url to the image.
|
|
|
|
Call `getInfo(id)` to grab the artist/album info. This will return the
|
|
text description.
|
|
|
|
The basic format for art in the cache is `<musicbrainzid>.<date>.<ext>`
|
|
and for info it is `<musicbrainzid>.<date>.txt`
