== Apache suEXEC ==

Setting the TRAC_ENV environment variable has described in TracInstall will not work when using [http://httpd.apache.org/docs/suexec.html Apache suEXEC] feature because the environment variables are filtered and only a subset reaches the cgi program.

So, we have two choices:
 * Recompile suexec to let it pass the TRAC_ENV variable, not advised, so I'll not explain how to do it.
 * Change our trac.cgi script to set the TRAC_ENV variable by itself, to do this we edit trac.cgi file and add

{{{
import os;os.environ['TRAC_ENV'] = '/path/to/projectenv'
}}}

before the `try:' line.
