### Sample Trac configuration taken from http://trac.edgewall.org/wiki/TracModPython    
###

### The recommended Trac web interface requires mod_python
<IfModule mod_python.c>

### Create your Trac environments as subdirectories of /var/trac
### They will appear in a listing on your website at /trac/, and be available 
### at /trac/PROJECTNAME/
<Location /trac>
    SetHandler mod_python
    PythonInterpreter main_interpreter
    PythonHandler trac.web.modpython_frontend 
    PythonOption TracEnvParentDir /var/www/trac
    PythonOption TracUriRoot /trac
</Location>

### Use htpasswd to add Trac accounts to the AuthUserFile
<LocationMatch "/trac/[^/]+/login">
    AuthType Basic
    AuthName "Trac"
    AuthUserFile /var/www/trac/.htpasswd
    Require valid-user
</LocationMatch>
