NAME
     wnargv -- parse string into UNIX-style arguments

SYNOPSIS
     wn_parse_into_args(&argc,&argv,string)
     int argc;
     char *argv[];
     char string[];

     wn_argscpy(&out_argv,argc,in_argv)
     char *out_argv[],*in_argv[];
     int argc;

     wn_freeargs(argc,argv)
     int argc;
     char *argv[];

DESCRIPTION
     These routines create and operate on UNIX-style argc-argv arguments.

     "wn_parse_into_args" parses "string" into UNIX-style argc-argv 
     arguments.  "argc" is the number of arguments parsed, called the
     argument count.  "argv" is an array of argument strings, of
     length argc+1.  argv[argc] is always set to NULL.  Normally,
     argv[0] is interpreted as a command, while argv[1], argv[2], ...
     are interpreted as the command's arguments.

     Caution: "argv" is allocated from static memory, which is 
     re-used on each call to "wn_parse_into_args".  Thus, a
     call to "wn_parse_into_args" destroys the "argv" produced by
     previous calls.  Use "wn_argscpy" to prevent this.

     "wn_argscpy" places copy of "in_argv" into "out_argv".  "out_argv"
     is assumed to have "argc" arguments.  New memory for "out_argv"
     is allocated from the current memory group.

     "wn_freeargs" frees an "argv" from "wn_argscpy" (into the current
     memory group).
