5 This directory includes examples which show how to create and use safe
6 environments for safe (sand-boxed) execution of Scheme programs.
8 *Note* that the files in this directory are only suitable for
9 demonstration purposes, if you have to implement safe evaluation
10 mechanisms in important environments, you will have to do more than
11 shown here -- for example disabling input/output operations.
13 The descriptions below assume that you have a working copy of Guile
14 installed and available with the standard installation prefix
22 The main program, which executes the Scheme code in a file given on
23 the command line in a safe environment. The following command will
24 do that with the file `untrusted.scm' (see below.)
26 $ ./safe untrusted.scm
30 guile -s safe untrusted.scm
34 This file contains some Scheme code, which will be executed in a
35 safe environment by the `safe' script.
39 This file also contains Scheme code, but it tries to do evil things.
40 Evaluating this with the `safe' script will abort on those evil
