+Options:

+    -i, --id        id number of an album (eg., a1234) or an artist to download all his albums (eg., 5678).

+    -l, --list      text file with a list of ids to download (accept comments using #)

+    -k, --kzip      keep the zip files downloaded

+    -c, --cat       force regeneration of the Jamendo catalog (automatic if the

+    -h, --help      this message

+   

+How to:

+    - To get album id, go on Jamendo website, choose an album, look at the address bar of the web browser

+        (eg., https://www.jamendo.com/fr/list/a122411/circles) and copy the id beginning by a (a122411)

+    - To get album id, go on Jamendo website, choose an album, look at the address bar of the web browser
