QUICK START

To build:	./configure && make
To test:	make test
To run: 	./run tests/hello.idel
To install:	make install
To remove:	make uninstall
To start a jobber: bin/jobber (executed from this directory)
To stop it:     bin/kill-jobber


ABOUT

Idel is a virtual machine for safely and portably running untrusted
code.  This is not a new programming language, but a substrate for
existing ones.  It's designed to:

 * be relatively language neutral
 * control resource consumption
 * support mobility and persistence
 * need only an auditably small trusted computing base
 * yield small object files and fast execution
 * accommodate capability-based security in a coming release
 * be easy to incorporate in other programs, the way Tcl is.

See:
 notes/Overview.text    for more motivation.
 doc/tutorial.text      for an intro to Idel's assembly language.
 man idelasm            about invoking the assembler.
 man idelvm             about invoking the runtime.
 examples/borednet      for an example application (CPU sharing)
 doc/specification.text for an (incomplete) virtual machine spec.

This preview release isn't meant for serious use.  Some important
features are missing, and others will change incompatibly later on.

 contrib/		Contributed code.
 notes/			Design notes, mostly to myself.


PORTABILITY

This package needs GNU Make, Awk (any modern Awk, just not the ancient
AT&T `old awk'), and an ANSI C (C89) compiler to build.  Also, the
borednet example uses Python, and the test suite uses the C
preprocessor (cpp) that ought to come with your C compiler but
occasionally doesn't.

It's been tested on the following systems:

	CPU		OS		Compiler
	-----------	------------	------------
	i686		Linux 2.0.36	gcc 2.95.2
	i586		FreeBSD 4.2	gcc 2.95.2

Earlier versions were also tested on these, and may still work:

	i686		Win2k/Cygwin	gcc 2.95.3-5
	PowerPC		Darwin 1.2	gcc 2.7.2.1

If it doesn't work out of the box for you, please let me know.  I
don't expect the current code to work on non-32-bit computers without
a little fixing up.  (I'll get to that when I have such a machine to
test it on.)


ACKNOWLEDGEMENTS

Thanks to Steve Jenson, Ryan Ziegler, and Glyph Lefkowitz for test
accounts, and to Luke Gorrie for idelrun.el.
