Geraldo is still not available as installer or system package. So, you have two ways to install it:
Get the latest tarball available from:
https://sourceforge.net/project/showfiles.php?group_id=251460&package_id=307400
Then you can do the following steps to install it:
Linux
tar xvfz geraldo-latest.tar.gz cd geraldo sudo python setup.py install
This will copy Geraldo's packages inside Python packages path.
Windows
If you are using Windows, Geraldo is fully compatible. You just have to use a tarball uncompress tool, like 7-Zip you can download from:
http://www.7-zip.org/download.html
Once you have a tool to uncompress tarball files, you have to uncompress it, open a MS-DOS Prompty window in the folder you uncompress into and run the following command:
python setup.py install
Our version control is centralized on GitHub Social repository, in the following URL:
http://github.com/marinho/geraldo
To get the latest development version from repository server, you will need for Git version control system. Then you can run the following command in Shell or MS-DOS Prompty window:
git clone git://github.com/marinho/geraldo.git
A folder named geraldo will be in your current path with all Geraldo files inside.
Then you can go ahead and use the same commands from Option 1 to install in your system.
ReportLab
This is required, there is no chance you use Geraldo with no ReportLab installed.
Get it from the following URL:
http://www.reportlab.org/
The tested version is 2.1.
