+Commander S 0.0 README					-*- outline -*-

+
+
+			     Commander S
+                             ===========
+
+* Requirements
+
+  Before installing Commander S, you need to install the following
+  software:
+
+  - The current CVS version of scsh, the Scheme Shell.  The latest
+    release, version 0.6.6, contains two small bugs that prevent
+    Commander S from running correctly. Alternativly, you may apply
+    the patches listed in the last section of this README to your scsh
+    0.6.6 source tree.
+    (From <http://www.scsh.net>)
+
+  - Version 1.1.0 of install-lib, the scsh installation library
+    (From <http://lamp.epfl.ch/~schinz/scsh_packages/scsh-install-lib-1.1.0.tar.gz>)
+
+  - Version 0.6 of Sunterlib, the Scheme Untergrund library
+    (From <http://savannah.nongnu.org/download/sunterlib/sunterlib-0.6.tar.gz>)
+
+* Installation
+
+  Run the script install.scm from the top of the tarball:
+
+  ./install.scm
+
+  The only important option is --prefix to specify a directory where
+  files are installed. Use the --help options to see all possible
+  options.
+
+* Patches for scsh
+
+  The following patches fix two little bugs in the scsh source tree
+  found during the development of Commander S.
