Function svn_opt_print_generic_help3 

pub unsafe extern "C" fn svn_opt_print_generic_help3(
    header: *const c_char,
    cmd_table: *const svn_opt_subcommand_desc3_t,
    opt_table: *const apr_getopt_option_t,
    footer: *const c_char,
    pool: *mut apr_pool_t,
    stream: *mut FILE,
)

Print a generic (not command-specific) usage message to @a stream.

@todo Why is @a stream a stdio file instead of an svn stream?

If @a header is non-NULL, print @a header followed by a newline. Then loop over @a cmd_table printing the usage for each command (getting option usages from @a opt_table). Then if @a footer is non-NULL, print @a footer followed by a newline.

Use @a pool for temporary allocation.
