OpenERP is a free enterprise management software package. It covers all
domains for small to medium businesses; accounting, stock management,
sales, customer relationship, purchases, project management, etcetera.
This is the client application.

openerp-client requires openerp-server, and matplotlib is optional.

Note that you will get an error on startup if matplotlib is not installed, 
but the only functionality lost is presenting graphs.
