- !ruby/struct:SM::Flow::P 
  body: Set the handling of the ordering of options and arguments. A RuntimeError is raised if option processing has already started.
- !ruby/struct:SM::Flow::P 
  body: "The supplied value must be a member of GetoptLong::ORDERINGS. It alters the processing of options as follows:"
- !ruby/struct:SM::Flow::P 
  body: "<b>REQUIRE_ORDER</b> :"
- !ruby/struct:SM::Flow::P 
  body: Options are required to occur before non-options.
- !ruby/struct:SM::Flow::P 
  body: Processing of options ends as soon as a word is encountered that has not been preceded by an appropriate option flag.
- !ruby/struct:SM::Flow::P 
  body: For example, if -a and -b are options which do not take arguments, parsing command line arguments of '-a one -b two' would result in 'one', '-b', 'two' being left in ARGV, and only ('-a', '') being processed as an option/arg pair.
- !ruby/struct:SM::Flow::P 
  body: This is the default ordering, if the environment variable POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)
- !ruby/struct:SM::Flow::P 
  body: "<b>PERMUTE</b> :"
- !ruby/struct:SM::Flow::P 
  body: Options can occur anywhere in the command line parsed. This is the default behavior.
- !ruby/struct:SM::Flow::P 
  body: Every sequence of words which can be interpreted as an option (with or without argument) is treated as an option; non-option words are skipped.
- !ruby/struct:SM::Flow::P 
  body: For example, if -a does not require an argument and -b optionally takes an argument, parsing '-a one -b two three' would result in ('-a','') and ('-b', 'two') being processed as option/arg pairs, and 'one','three' being left in ARGV.
- !ruby/struct:SM::Flow::P 
  body: If the ordering is set to PERMUTE but the environment variable POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for compatibility with GNU getopt_long.
- !ruby/struct:SM::Flow::P 
  body: "<b>RETURN_IN_ORDER</b> :"
- !ruby/struct:SM::Flow::P 
  body: All words on the command line are processed as options. Words not preceded by a short or long option flag are passed as arguments with an option of '' (empty string).
- !ruby/struct:SM::Flow::P 
  body: For example, if -a requires an argument but -b does not, a command line of '-a one -b two three' would result in option/arg pairs of ('-a', 'one') ('-b', ''), ('', 'two'), ('', 'three') being processed.
