Working on Wrangler

First, get a TACC account, then get Peter to add you to the ATLAS_simulations project.
Login to wrangler (ssh username@wrangler.tacc.utexas.edu).
Make a ~/bin directory.
Copy the file ~ponyisi/cctools/cctools-5.3.2-x86_64-redhat6/bin/parrot_run to your ~/bin/ directory.
Run the following to get a "Parrotized" shell with CVMFS:
```
export HTTP_PROXY="http://utatlas.its.utexas.edu:3128;DIRECT"
$HOME/bin/parrot_run --cvmfs-repo-switching bash
```
(Note that you can replace "bash" with a script.) This will give you a new shell which has access to CVMFS.
To run the ATLAS localSetup, copy the file ~ponyisi/cctools/atlasinit to your local area, and run
```
source atlasinit
```
From that point on it should look just like a regular Tier-3 or workstation environment.
