 `FileIO` API (brief summary, see individual functions for more detail):
 
 - `format"PNG"`: specifies a particular defined format
-- `File{fmt}` and `Stream{fmt}`: types of objects that declare that a resource has a particular format `fmt`
+- [`File{fmt}`](@ref) and [`Stream{fmt}`](@ref): types of objects that declare that a resource has a particular format `fmt`
 
-- `load([filename|stream])`: read data in formatted file, inferring the format
+- [`load([filename|stream])`](@ref): read data in formatted file, inferring the format
 - `load(File{format"PNG"}(filename))`: specify the format manually
-- `loadstreaming([filename|stream])`: similar to `load`, except that it returns an object that can be read from
-- `save(filename, data...)` for similar operations involving saving data
-- `savestreaming([filename|stream])`: similar to `save`, except that it returns an object that can be written to
+- [`loadstreaming([filename|stream])`](@ref): similar to `load`, except that it returns an object that can be read from
+- [`save(filename, data...)`](@ref) for similar operations involving saving data
+- [`savestreaming([filename|stream])`](@ref): similar to `save`, except that it returns an object that can be written to
 
 - `io = open(f::File, args...)` opens a file
-- `io = stream(s::Stream)` returns the IOStream from the query object `s`
+- [`io = stream(s::Stream)`](@ref stream) returns the IOStream from the query object `s`
 
-- `query([filename|stream])`: attempt to infer the format of `filename`
-- `unknown(q)` returns true if a query can't be resolved
-- `skipmagic(io, fmt)` sets the position of `io` to just after the magic bytes
-- `magic(fmt)` returns the magic bytes for format `fmt`
-- `info(fmt)` returns `(magic, extensions)` for format `fmt`

-- `add_format(fmt, magic, extension, libraries...)`: register a new format
-- `add_loader(fmt, :Package)`: indicate that `Package` supports loading files of type `fmt`
