Ganga is an enhanced python interpreter, designed for job submission to the GRID. It is made with the philosophy of: write options file once, deploy everywhere. To run Ganga, simply type:

SetupProject Ganga
ganga

Once Ganga is set up, one only needs to type ganga to start the interpreter. Ganga can also be run in batch mode by typing:

ganga script.py

or by invoking Ganga as an environment variable with the usual #!/usr/bin/env ganga.

Options file

An options file (so-called for historical reasons) is a Python file designed to be run using LHCb software. It is essentially a small script detailing what you want to happen. Option files call in other LHCb software via the import function in Python.
