-This directory contains the distribution of scm5e5.  SCM conforms to
-Revised^5 Report on the Algorithmic Language Scheme and the IEEE P1178
-specification.  SCM runs under Amiga, Atari-ST, MacOS, MS-DOS, OS/2,
-NOS/VE, Unicos, VMS, Unix and similar systems.  SCM supports the SLIB
-Scheme library; both SCM and SLIB are GNU packages.

-2.2 SLIB
-========
-
-[SLIB] is a portable Scheme library meant to provide compatibility and
-utility functions for all standard Scheme implementations.  Although
-SLIB is not _neccessary_ to run SCM, I strongly suggest you obtain and
-install it.  Bug reports about running SCM without SLIB have very low
-priority.  SLIB is available from the same sites as SCM:
-
-   * swiss.csail.mit.edu:/pub/scm/slib-3b1.tar.gz
-
-   * ftp.gnu.org:/pub/gnu/jacal/slib-3b1.tar.gz
-
-Unpack SLIB (`tar xzf slib-3b1.tar.gz' or `unzip -ao slib-3b1.zip') in
-an appropriate directory for your system; both `tar' and `unzip' will
-create the directory `slib'.
-
-Then create a file `require.scm' in the SCM "implementation-vicinity"
-(this is the same directory as where the file `Init5e5.scm' is
-installed).  `require.scm' should have the contents:
-
-     (define (library-vicinity) "/usr/local/lib/slib/")
-
-where the pathname string `/usr/local/lib/slib/' is to be replaced by
-the pathname into which you installed SLIB.  Absolute pathnames are
-recommended here; if you use a relative pathname, SLIB can get confused
-when the working directory is changed (*note chmod: I/O-Extensions.).
-The way to specify a relative pathname is to append it to the
-implementation-vicinity, which is absolute:
-
-     (define library-vicinity
-       (let ((lv (string-append (implementation-vicinity) "../slib/")))
-         (lambda () lv)))
-
-Alternatively, you can set the (shell) environment variable
-`SCHEME_LIBRARY_PATH' to the pathname of the SLIB directory (*note
-SCHEME_LIBRARY_PATH: SCM Variables.).  If set, the environment variable
-overrides `require.scm'.  Again, absolute pathnames are recommended.
-

-
-2.1 Making SCM
-==============
-
-The SCM distribution has "Makefile" which contains rules for making
-"scmlit", a "bare-bones" version of SCM sufficient for running `build'.
-`build' is used to compile (or create scripts to compile) full
-featured versions (*note Building SCM::).
-
-Makefiles are not portable to the majority of platforms.  If `Makefile'
-works for you, good; If not, I don't want to hear about it.  If you
-need to compile SCM without build, there are several ways to proceed:
-
-   * Use the build (http://swiss.csail.mit.edu/~jaffer/buildscm.html)
-     web page to create custom batch scripts for compiling SCM.
-
-   * Use SCM on a different platform to run `build' to create a script
-     to build SCM;
-
-   * Use another implementation of Scheme to run `build' to create a
-     script to build SCM;
-
-   * Create your own script or `Makefile'.

-
-3.7 Editing Scheme Code
-=======================
-
- -- Function: ed arg1 ...
-     The value of the environment variable `EDITOR' (or just `ed' if it
-     isn't defined) is invoked as a command with arguments ARG1 ....
-
- -- Function: ed filename
-     If SCM is compiled under VMS `ed' will invoke the editor with a
-     single the single argument FILENAME.
-
-Gnu Emacs:
-     Editing of Scheme code is supported by emacs.  Buffers holding
-     files ending in .scm are automatically put into scheme-mode.
-
-     If your Emacs can run a process in a buffer you can use the Emacs
-     command `M-x run-scheme' with SCM.  Otherwise, use the emacs
-     command `M-x suspend-emacs'; or see "other systems" below.
-
-Epsilon (MS-DOS):
-     There is lisp (and scheme) mode available by use of the package
-     `LISP.E'.  It offers several different indentation formats.  With
-     this package, buffers holding files ending in `.L', `.LSP', `.S',
-     and `.SCM' (my modification) are automatically put into lisp-mode.
-
-     It is possible to run a process in a buffer under Epsilon.  With
-     Epsilon 5.0 the command line options `-e512 -m0' are neccessary to
-     manage RAM properly.  It has been reported that when compiling SCM
-     with Turbo C, you need to `#define NOSETBUF' for proper operation
-     in a process buffer with Epsilon 5.0.
-
-     One can also call out to an editor from SCM if RAM is at a
-     premium; See "under other systems" below.
-
-other systems:
-     Define the environment variable `EDITOR' to be the name of the
-     editing program you use.  The SCM procedure `(ed arg1 ...)' will
-     invoke your editor and return to SCM when you exit the editor.  The
-     following definition is convenient:
-
-          (define (e) (ed "work.scm") (load "work.scm"))
-
-     Typing `(e)' will invoke the editor with the file of interest.
-     After editing, the modified file will be loaded.

-Sparc(SUN-4) heap is growing out of control
-     You are experiencing a GC problem peculiar to the Sparc.  The
-     problem is that SCM doesn't know how to clear register windows.
-     Every location which is not reused still gets marked at GC time.
-     This causes lots of stuff which should be collected to not be.
-     This will be a problem with any _conservative_ GC until we find
-     what instruction will clear the register windows.  This problem is
-     exacerbated by using lots of call-with-current-continuations.  A
-     possible fix for dynthrow() is commented out in `continue.c'.
