This directory contains code with persistent data structures that are primarily meant to be used for buffer implementation, but may also be used as just balanced trees.
To use any of these buffer implementations (binseq-buffer or obinseq-buffer), pass them as the :implementation argument when instatiating climacs-buffer class in pane.lisp.
NOTE: There is a dependency of Persistent/persistent-buffer.lisp on Flexichain/utilities.lisp (the weak pointer handling).
A more live version at Drei.
