[migration] move 'entities' table changes from 3.19.0 to bootstrap script
The 'mtime' and 'source' columns need to go away before we attempt to do
anything else with the repo, otherwise any addition of an entity is
going to explode.
About this site
===============
This web application is based on the CubicWeb knowledge management system
from Logilab_. CubicWeb is made of an object database and a web
framework. It allows to develop an application by defining a set of
entities and their relationships, plus a set of views that present the
data selected from the object database using a specific query language.
This application has a precise schema_ and can be considered an
example of a semantic web database, as it can export the data to XML
and others formats and is not limited to publishing HTML.
