## [read($fh)](#read%28$fh%29)

Reads the anchor from the given file handle at that point. The file handle is left at an arbitrary read point, usually the end of something!

## [out($fh, $style)](#out%28$fh,_$style%29)

Outputs the Anchor to the given file handle at this point also addressing issues of deltas. If $style is set, then no output is sent to the file handle. The return value is the output string.
