New install, Wheezy:i386

three uers on the system, includes root. "/opt/trintity/" only gets 
added to the PATH of one user. No mention of trinity stuff 
in  "~.bashrc, ~.profile, /etc/profile, /etc/bash.bashrc". 

 I know how to change the PATH using the above files, want to know how 
TDE does it, or fails to, on install.

TIA
