About OtterSR
What this software is built from, and the licences it carries.
Derived from CAN-SR
OtterSR is a rebuild of CAN-SR, a systematic review tool released under the MIT licence. That licence requires its copyright notice to travel with every copy, including this one, so it is reproduced in full below.
OtterSR is an independent product. It is not affiliated with, endorsed by, or sponsored by the Public Health Agency of Canada or the Government of Canada, and it carries none of their branding. The MIT licence grants no trademark rights.
