Drei - an acronym for /Drei Replaces EINE's Inheritor/ - is one of the
editor substrates provided by McCLIM. Drei is activated by default.

System provides lisp syntax analysis facilities. One of them depends
on the 'SWANK', which is a system's dependency. If you want to build
the system without 'SWANK', push ':CLIM-WITHOUT-SWANK' to the
'*FEATURES*' before loading the system.

input-editing-drei.lisp contains deprecated implementation of the input editing
protocol for CLIM. Use at your own risk. It depends on systems "clim-core" and
"drei-mcclim".
