# Installation¶

This library is an extension of ASE. A working version must be installed before use of TSASE.

A read-only copy of the code can be anonymously checked out of the subversion repository with the following command:

svn co http://theory.cm.utexas.edu/svn/tsase


If you are a developer you can checkout the code using the command:

svn co svn+ssh://username@theory.cm.utexas.edu/svn/tsase


This will fetch a copy of the latest code to a local directory named tsase.

Once you have a local copy of tsase, include the top directory to your $PYTHONPATH. To use the independent scripts, it is recommended to add $HOME/tsase/tsase/bin to your $PATH: export PYTHONPATH=$HOME/tsase:$PYTHONPATH export PATH=$HOME/tsase/bin:\$PATH
