This directory tree contains the documentation for Elk as troff source
and PostScript hardcopy files.
You need a troff and the ms macro package to build the documentation
from the troff source (see the Makefile in each subdirectory). The
files ending in .ps are pre-generated PostScript files; you can send
them directly to a PostScript printer or browse them with a PostScript
previewer. The PostScript file have been generated with GNU groff.
As a courtesy to our US audience, the PostScript files are in US
letter format. If you don't like this (and your groff default is A4),
deactivate the ".pl 11i" directives in util/tmac.scheme,
usenix/usenix.ms, and man/elk.1 (i.e. insert a comment token before it)
and rebuild the document(s).
All the documents have been prepared for translation to HTML using
the Elk-based `unroff' package (see ../README for availability
information).
kernel/ The Scheme Reference for Elk. It describes the Scheme language
dialect implemented by the Scheme interpreter included in
Elk (a superset of the official language).
usenix/ A paper about Elk that has appeared in USENIX Computing
Systems (vol. 7, no. 4, pp. 419-449, 1994).
man/ This directory holds a brief online manual page for the Scheme
interpreter component. You may want to install in `/usr/share/man'
on your system. The manual page essentially describes the
command line options of the interpreter.
xlib/ The reference manual for the Xlib extension to Elk.
xt/ The reference manual for the Xt (X11 Toolkit Intrinsics)
extension to Elk.
unix/ The reference manual for the UNIX extension.
record/ The reference manual for the record extension.
bitstring/ The reference manual for the bit string extension.
regexp/ The reference manual for the regular expression extension.
oops/ A manual for the simple Scheme-based object oriented programming
tool included in Elk (oops.scm).
cprog/ The C/C++ Programmer's Manual for Elk. This comprehensive
manual describes the facilities of the C/C++ interface of
Elk. Topics range from the general architecture of Elk-based
applications and defining application-specific Scheme types
and primitives, to more advanced subjects such as interacting
with the garbage collector. The audience are authors of
Elk-based applications and extension writers.
This manual is a replacement for the document that lived in
a subdirectory `ex' in earlier version of Elk.
util/ A collection of troff macro files and other utilities needed
for typesetting the documentation in the above directories.
There is a small C program `mkindex.c' that is required to
build the C/C++ Programmer's Manual (cprog/cprog.ms); you
will have to compile it by calling "make" if you must typeset
the manual. See the comment at the beginning of util/mkindex.c
for a brief explanation of what it does.
