       getflags, usage - command-line parsing for shell scripts

       aux/getflags $*


       Getflags	 parses the options in its command-line arguments according to
       the environment variable $flagfmt.  This variable should be a  list  of
       comma-separated	options.  Each option can be a single letter, indicat‐
       ing that it does not take arguments, or a letter followed by the space-
       separated  names	 of its arguments.  Getflags prints an rc(1) script on
       standard output which initializes the environment variable  $flagx  for
       every  option  mentioned	 in $flagfmt.  If the option is not present on
       the command-line, the script sets that option's	flag  variable	to  an
       empty  list.   Otherwise,  the  script sets that option's flag variable
       with a list containing the option's arguments or, if the	 option	 takes
       no  arguments, with the string 1.  The script also sets the variable $*
       to the list of arguments following the options.	The final line in  the
       script sets the $status variable, to the empty string on success and to
       the string usage when there is an error parsing the command line.

       Usage prints a usage message to standard error.	It creates the message
       using  $flagfmt,	 as  described	above, $args, which should contain the
       string to be printed explaining non-option arguments, and $0, the  pro‐
       gram name (see rc(1)).

       Parse the arguments for leak(1):

	      flagfmt='b,s,f binary,r res,x width'
	      args='name | pid list'
	      if(! ifs=() eval `{aux/getflags $*} || ~ $#* 0){
		   exit usage
