Question : pro*c demo file missing

Hi,

On Solaris 64, With Oracle 10.2.0.4

a third party vendor has developed a pro*c program that is using files from the following directory:
$ORACLE_HOME/precomp/demo/proc

This directory is missing from my installation.
Does anyone know were can I download them from?
I did not find it on any patch or installation file from support.oracle.com

Thanks

Answer : pro*c demo file missing

starting with v. ~10 (i believe) oracle removed the "demo progs" from the main server installation and put em on the companion cd, available here:
