Osmosis is a command line java app for processing OSM data. The tool
consists of a series of pluggable components that can be chained together
to perform a larger operation. For example, it has components for reading
from database and from file, components for writing to database and to file,
components for deriving and applying change sets to data sources, components
for sorting data, etc. It has been written so that it is easy to add new
features without re-writing common tasks such as file or database handling.
