Installing trytond-sale-invoice-cancel ====================================== Prerequisites ------------- * Python 2.6 or later (http://www.python.org/) * trytond (http://www.tryton.org/) Installation ------------ Once you've downloaded and unpacked the trytond_helloword source release, enter the directory where the archive was unpacked, and run: python setup.py install Note that you may need administrator/root privileges for this step, as this command will by default attempt to install module to the Python site-packages directory on your system. For advanced options, please refer to the easy_install and/or the distutils documentation: http://peak.telecommunity.com/DevCenter/EasyInstall http://docs.python.org/inst/inst.html To use without installation, extract the archive into ``trytond/modules`` with the directory name sale_invoice_cancel.
