USING PASSWORDS
 
 FTP
 
   To ftp files using name+passwd, include them in the URL like:
 
        curl ftp://name:[email protected]:port/full/path/to/file
 
   or specify them with the -u flag like
 
        curl -u name:passwd ftp://machine.domain:port/full/path/to/file
 
 FTPS
 
   It is just like for FTP, but you may also want to specify and use
   SSL-specific options for certificates etc.
 
   Note that using FTPS:// as prefix is the "implicit" way as described in the
   standards while the recommended "explicit" way is done by using FTP:// and
   the --ftp-ssl option.
