Hello,
At http://chicken.wiki.br/writing%20portable%20scripts we have a
section called "Writing portable scripts with env" whose instructions
doesn't seem to be very portable.
At least it doesn't work on my system:
$ ./s.scm
/usr/bin/env: csi -s: No such file or directory
$ cat s.scm
#! /usr/bin/env csi -s
(print (argv))
There's a discussion on the guile mailing list about this topic:
http://sourceware.org/ml/guile/1997-11/msg00034.html
If nobody has objections, I'll remove the "Writing portable scripts
with env" section from the wiki.
