Introduction

  This is the user's manual for psd, the Portable Scheme Debugger. Psd is a source level debugger for the Scheme language, based on instrumenting the original source code. Psd is placed under the GNU General Public License (``copyleft''), so you are free to use, distribute and modify it as long as you let other people do it, too. See the file COPYING in the psd distribution for more details.

This manual describes version 1.1 of psd. To see what has changed from version 1.0, see end of this manual.
