*****************************************************************
TWiki has been installed in ${TWIKIDIR}, with a sample
configuration file in ${TWIKIDIR}/lib/TWiki.cfg.sample
You need to copy this file to ${TWIKIDIR}/lib/TWiki.cfg
and possibly edit it before your installation will be complete.

In most cases, you can simply type:

cp ${TWIKIDIR}/lib/TWiki.cfg.sample ${TWIKIDIR}/lib/TWiki.cfg

Then you should be able to visit http://${HOSTNAME}/twiki/

You need to setup your webserver correctly for TWiki to work
An example for apache is below:

ScriptAlias /twiki/bin/ "${PKG_PREFIX}/www/twiki/bin/"
Alias /twiki/ "${PKG_PREFIX}/www/twiki/"
<Directory "${PKG_PREFIX}/www/twiki/bin">
  Options +ExecCGI
  SetHandler cgi-script
  Allow from all
  SetEnv USER "${WWWUSER}"
</Directory>
<Directory "${PKG_PREFIX}/www/twiki/pub">
  Options FollowSymLinks +Includes
  AllowOverride None
  Allow from all
</Directory>

Note that this default configuration defines a completely
open TWiki - any visitor may make changes. Please consult the
documentation for other configuration options if this is not the
desired mode of operation.

Please visit http://TWiki.org/feedback.html and leave feedback
on your experiences with TWiki.

Good Luck!
