To run Fossil as CGI, create a CGI script (here called "repo") in the CGI directory
of your web server and having content like this:
<blockquote><pre>
#!/usr/bin/fossil
repository: /home/fossil/repo.fossil
</pre></blockquote>
</p>

<p>
As always, adjust your paths appropriately.
It may be necessary to set permissions properly, or to modify an ".htaccess"
file or make other server-specific changes.  Consult the documentation
for your particular web server. In particular, the following permissions are
<em>normally</em> required (but, again, may be different for a particular
configuration):

<ul>
<li>The Fossil binary must be readable/executable, and ALL directories leading up to it
must be readable by the process which executes the CGI.</li>
<li>ALL directories leading to the CGI script must also be readable and the CGI
script itself must be executable for the user under which it will run (which often differs
from the one running the web server - consult your site's documentation or administrator).</li>
<li>The repository file AND the directory containing it must be writable by the same account
which executes the Fossil binary (again, this might differ from the WWW user). The directory
needs to be writable so that sqlite can write its journal files.</li>
</ul>
</p>

<p>
Once the script is set up correctly, and assuming your server is also set
correctly, you should be able to access your repository with a URL like:
<b>http://mydomain.org/cgi-bin/repo</b> (assuming the "repo" script is
accessible under "cgi-bin", which would be a typical deployment on Apache
for instance).
</p>
