Atlassian Sourcetree is a free Git and Mercurial client for Windows.

Atlassian Sourcetree is a free Git and Mercurial client for Mac.

This is the standalone Sage Notebook.

Most of the notebook does not depend on having Sage installed. Only a few miscellaneous functions are imported from Sage. We welcome help in making the notebook completely independent from Sage, or indeed, any other help with the Sage notebook. Sage notebook development discussions happen on the sage-notebook mailing list.

## Installation

Install Sage, then do `sage -python setup.py install` in the current
directory. Then run the notebook from within Sage as follows:

sage: import sagenb.notebook.notebook_object as nb sage: nb.notebook(directory="mynotebook")

This will create a directory mynotebook.sagenb, and all notebook data is stored in that directory.

### SSL support

SSL is required for OpenID and accessing HTTPS from the Sage shell. Your
Sage install should usually support SSL out of the box, but if you
compiled it from source on a machine without the libssl headers, it may
not. You can check for SSL support by running `import ssl` in the Sage
console. If you get an error, then do the following.

- Install the libssl headers on your system. On Debian-based systems,
one way to do this is to run
`sudo apt-get install libssl-dev`. - Recompile Sage's internal Python interpreter by running
`sage -f python`.
