Dabo will be installed using the Python distutils - python setup.py install, but that isn't set up yet, so here is a quick blurb to get you going. Dabo is a runtime library, which your applications will import using standard Python syntax. Therefore, it needs to be in PYTHONPATH, so that your 'import dabo' statements will find it. The easiest way to do this is to put dabo into your Python installation's site-packages directory. The easiest way to find out where this is on your system (yes, it varies, so we can't just tell you where it is) is to start Python and query sys.path. For instance: [pmcnett@sol dabo]$ python Python 2.3.2 (#1, Oct 6 2003, 10:07:16) [GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/home/pmcnett/dl/python/wxPythonSrc-2.5.1.5/wxPython', '/usr/lib/python23.zip', '/usr/lib/python2.3', '/usr/lib/python2.3/plat-linux2', '/usr/lib/python2.3/lib-tk', '/usr/lib/python2.3/lib-dynload', '/usr/lib/python2.3/site-packages', '/usr/lib/python2.3/site-packages/PythonCAD', '/usr/local/gnue/lib/python'] I can see that my site-packages directory is installed in /usr/lib/python2.3/site-packages. So I can then copy or symlink the dabo root directory there to make it importable. You will likely need administrative privileges to do this on your system, unless you happen to be running Windows. If you would rather put dabo somewhere else, you can put a text file called dabo.pth inside your Python site-packages directory. The contents of this file must specify the parent directory where Dabo can be found. For instance, if you put Dabo in c:\programs\myprogs\dabo, you'll need your dabo.pth to say 'c:\programs\myprogs'.
