# aria2 identifies each download by the ID called GID.
# The GID must be hex string of 16 characters,
# thus [0-9a-zA-Z] are allowed and leading zeros must 
# not be stripped. The GID all 0 is reserved and must
# not be used. The GID must be unique, otherwise error 
# is reported and the download is not added.
# gidGenerator generates GID for downloads
