If you turn on trace(3), exu will try to create a
"ctrace.out" file in the current directory.
ex.err is only produced when there's an error.

File permissions on Linux/FreeBSD can be tricky.
The process that runs your Euphoria CGI program
probably runs as a different user id than you.

On RapidEuphoria.com (FreeBSD) CGI programs run
under user "nobody" with the group set to one that
both "nobody" and my user id belong to. I don't know
what permissions files in /usr/local/www might have, but to
write a new file in a directory, the CGI program will
need write permission on the directory itself.

For me, all my CGI programs are in cgi-bin, and that's where
ex.err, ex.pro and ctrace.out appear. There's a file called
.htaccess in cgi-bin that gives permission for
CGI programs to run from cgi-bin. I believe .htaccess is
an Apache-defined thing.

I store a copy of exu plus the .e files from euphoria/include
in cgi-bin, because "nobody" doesn't know about "EUDIR",
nor does it have euphoria/bin on its path. I don't
own the machine that runs RapidEuphoria.com,
I'm just an ordinary user.
