+
+		Welcome to the Scsh CVS Repository !!!
+
+
+
+This file contains some instructions about how to build Scsh after you
+freshly checked out the "scsh-0.6" module. These instructions do *not*
+apply to the module named "scsh" or the Scsh distribution itself.
+
+There is currently no scheme to tag working snapshots of the
+repository, so anything may happen during the build process. The scsh
+team does in general *not* provide support for code obtained from the
+CVS repository.
+
+During the build process a number of auto generated files not included
+in the CVS repository are built. It is highly recommended to follow
+these instructions carefully otherwise incompatible versions of
+generated files will result.
+
+To build Scsh, proceed as follows:
+
+1.) You must have a working version of Scheme 48, version 0.53. If you
+    don't have, get it from http://www.s48.org/0.53/scheme48-0.53.tgz
+    and install Scheme 48. Change to value of the variable
+    BUILD_RUNNABLE in Makefile.in so that it will point to the Scheme
+    48 executable.
+
+2.) "cd" into the directory which contains the source code (normally
+    scsh-0.6) and run the script autogen.sh:
+
+    ./autogen.sh
+
+    This will take several minutes and generate the source code for
+    the virtual machine and two images the Makefile relies
+    on. Furthermore the configure file will be generated.
+
+3.) Configure the system:
+
+    ./configure
+
+    You presumably want to add the --prefix flag here to determine the
+    installation directory. This will generate the Makefile.
+
+4.) Build the system:
+
+    make
+
+    If anything fails here, fix the problem and/or contact the authors.
+
+5.) You should have a runnable version of the system that can be
+    started in the build directory like this:
+
+    ./go
+
+    To be sure, everything is up-to-date, touch all Scheme files in
+    the subdirectory scsh:
+
+    touch scsh/*.scm scsh/*/*.scm
+
+    and rebuild the system according to step 4.
+
+6.) To install Scsh, type:
+
+    make install
+
+    Note that it is not recommended to have a CVS version of Scsh for
+    daily use.
+
+You should repeat the whole build process whenever there are changes
+to files in the directories scheme/vm, scheme/rts or
+scheme/bcomp. Watch the run of cvs update carefully and/or subscribe
+to the list scsh-checkins@lists.sourceforge.net.
+
+
+Enjoy!!!
