Introduction to the PSI3 Repository

The main repository for the PSI3 Source code is currently maintained by the Crawford group at Virginia Tech. To check out the code, one must first obtain a CVS account by emailing psimaster@sirius.chem.vt.edu. After you have a login-id and password, set the CVSROOT environmental variable for your shell to point to the main repository:

For csh/tcsh:

setenv CVSROOT :pserver:login@sirius.chem.vt.edu:/home/users/psi3/master

For sh/bash:

CVSROOT=:pserver:login@sirius.chem.vt.edu:/home/users/psi3/master
export CVSROOT

where login is your login name. Next, provide a password to the CVS server by typing cvs login. (Subsequent requests to the repository will not require you to re-login.)

Check out a complete PSI3 source copy by running

cvs co psi3

The working copy will be placed in the directory psi3. We will refer to this directory from now on as $PSI3.
