Using calibre in your projects
----------------------------------------
It is possible to directly use calibre functions/code in your python project. Two ways exist to do this:
Binary install of calibre
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you have a binary install of calibre, you can use the python interpreter bundled with calibre, like this::
calibre-debug -e /path/to/your/python/script.py
Source install on linux
^^^^^^^^^^^^^^^^^^^^^^^^^^
In addition to using the above technique, if you do a source install on linux,
you can also directly import calibre, as follows::
import init_calibre
import calibre
print calibre.__version__
It is essential that you import the init_calibre module before any other calibre modules/packages as
it sets up the interpreter to run calibre code.
