OptionParser.t parses command line options.  For more details, please use the --help option, or try 'perldoc $PROGRAM_NAME' for complete documentation.
Usage: $PROGRAM_NAME <options>

Options:

  --bar=d  DSN bar
  --foo=d  DSN foo

Option types: s=string, i=integer, f=float, h/H/a/A=comma-separated list, d=DSN, z=size, m=time

Rules:

  DSN values in --foo default to values in --bar if COPY is yes.

DSN syntax is key=value[,key=value...]  Allowable DSN keys:

  KEY  COPY  MEANING
  ===  ====  =============================================
  A    yes   Default character set
  D    yes   Database to use
  F    yes   Only read default options from the given file
  P    yes   Port number to use for connection
  S    yes   Socket file to use for connection
  h    yes   Connect to host
  p    yes   Password to use when connecting
  u    yes   User for login if not current user

  If the DSN is a bareword, the word is treated as the 'h' key.

Options and values after processing arguments:

  --bar    (No value)
  --foo    (No value)
