-
-Usage: $executable [options] <ini file>
-
-	$executable [options] <ini file>
-		Runs a complete PRO optimization using the ini file specified.
-
-Required:
-
-	--ref-files <files>
-		Dev set ref files.  This option takes only a single string argument.
-		To use multiple files (including file globbing), this argument should
-		be quoted.
-
-	--source-file <file>
-		Dev set source file.
-
-	--weights <file>
-		Initial weights file (use empty file to start from 0)
-
-General options:
-
-	--help
-		Print this message and exit.
-
-	--dont-accumulate
-		Don't accumulate k-best lists from multiple iterations.
-
-	--max-iterations <M>
-		Maximum number of iterations to run.  If not specified, defaults
-		to $default_max_iter.
-
-	--metric <method>
-		Metric to optimize.
-		Example values: IBM_BLEU, NIST_BLEU, Koehn_BLEU, TER, Combi
-
-	--pass-suffix <S>
-		If the decoder is doing multi-pass decoding, the pass suffix "2",
-		"3", etc., is used to control what iteration of weights is set.
-
-	--workdir <dir>
-		Directory for intermediate and output files.  If not specified, the
-		name is derived from the ini filename.  Assuming that the ini
-		filename begins with the decoder name and ends with ini, the default
-		name of the working directory is inferred from the middle part of
-		the filename.  E.g. an ini file named decoder.foo.ini would have
-		a default working directory name foo.
-
-Regularization options:
-
-	--reg <F>
-		l2 regularization strength [default=500]. The greater this value,
-		the closer to zero the weights will be.
-
-Job control options:
-
-	--jobs <I>
-		Number of decoder processes to run in parallel. [default=$default_jobs]
-
-	--qsub
-		Use qsub to run jobs in parallel (qsub must be configured in
-		environment/LocalEnvironment.pm)
-
-	--pmem <N>
-		Amount of physical memory requested for parallel decoding jobs
-		(used with qsub requests only)
