  10  * Front-end modes and global usage
  11  *
  12  * The front end might be in one of three modes: FS, repod, or S3.  FS mode
  13  * is distinguished from the other two by having proxy_host=NULL.  (In fact
  14  * what the "-f" flag does is set cfg_file=NULL, which suppresses parsing of
  15  * the config file; it's the parser that sets proxy_host to some other value.)
  16  * If proxy_host!=NULL then proxy_port and s3mode are also valid.  If s3mode
  17  * in turn is non-zero then proxy_key and proxy_secret are also valid.  I've
  18  * marked the relevant globals with the modes where they're valid.
  19  *
  20  * NONE OF THIS affects the back ends used for replication.  There can be
  21  * multiple such back ends, each individually repod or S3 mode with their
  22  * own keys/secrets.
