+@defun getopt->parameter-list optnames arities types aliases desc @dots{}
+
+Returns @var{*argv*} converted to a parameter-list.  @var{optnames} are
+the parameter-names.  @var{arities} and @var{types} are lists of symbols
+corresponding to @var{optnames}.
+
+@var{aliases} is a list of lists of strings or integers paired with
+elements of @var{optnames}.  Each one-character string will be treated
+as a single @samp{-} option by @code{getopt}.  Longer strings will be
+treated as long-named options (@pxref{Getopt, getopt--}).
+
+If the @var{aliases} association list has only strings as its
+@code{car}s, then all the option-arguments after an option (and before
+the next option) are adjoined to that option.
+
+If the @var{aliases} association list has integers, then each (string)
+option will take at most one option-argument.  Unoptioned arguments are
+collected in a list.  A @samp{-1} alias will take the last argument in
+this list; @samp{+1} will take the first argument in the list.  The
+aliases -2 then +2; -3 then +3; @dots{} are tried so long as a positive
+or negative consecutive alias is found and arguments remain in the list.
+Finally a @samp{0} alias, if found, absorbs any remaining arguments.
+
+In all cases, if unclaimed arguments remain after processing, a warning
+is signaled and #f is returned.
+@end defun
+
+@defun getopt->arglist optnames positions arities types defaulters checks aliases desc @dots{}
+
+Like @code{getopt->parameter-list}, but converts @var{*argv*} to an
+argument-list as specified by @var{optnames}, @var{positions},
+@var{arities}, @var{types}, @var{defaulters}, @var{checks}, and
+@var{aliases}.  If the options supplied violate the @var{arities} or
+@var{checks} constraints, then a warning is signaled and #f is returned.
+@end defun
+@noindent
+These @code{getopt} functions can be used with SLIB relational
+databases.  For an example, @xref{Using Databases, make-command-server}.
+
+@noindent
+If errors are encountered while processing options, directions for using
+the options (and argument strings @var{desc} @dots{}) are printed to
+@code{current-error-port}.
