To install senaite.lis2a in your SENAITE instance, simply add this add-on in your buildout configuration file as follows, and run bin/buildout afterwards:
[buildout] ... [instance] ... eggs = ... senaite.lis2a
With this configuration, buildout will download and install the latest published release of senaite.lis2a from Pypi.
For high-demand instances, is strongly recommended to use this add-on together with senaite.queue. senaite.lis2a delegates the import of results to senaite.queue when installed and active. Otherwise, the import of results takes place in a single transaction as soon as the data is received.
