+/* getargs.c
+
+   This replaces the original parse.c.  It is little more compact and with
+   a minor change it will parse quoted or unquoted arguments (double quotes,
+   ("). If there is nothing between two sets of quotes (""), the field is
+   replaced with the '\0' character and parsing continues.  This routine was
+   originally posted to comp.lang.c by Steve Summit <scs@eskimo.c>.  Thanks
+   to Steve for his okey dokey to use it in UUCPbb.
