Hello,

I reworked on my code. You can find it here : https://pypi.python.org/pypi/python-gantt/

or with pip ::

  pip install python-gantt


Enclosed, there is two parts :

- python-gantt : this library is used to draw gantt svg charts from python
- org2gantt : used to transform org-mode files to python-gantt ones


You can see outputs here :

 - http://xael.org/norman/python/python-gantt/project_resources.png
 
Installation
------------

To install python-gantt, just issue :

  python setup.py install

It requires :
- svgwrite
- clize

Usage
-----

For using org2gantt, see help :

  python org2gantt/org2gantt.py -h


Basic usage is :

  python org2gantt/org2gantt.py org2gantt/example.org

It should generate two charts : one for tasks and one for resources assignment.


Syntax for org-mode
-------------------

See org2gantt/example.org and org2gantt/README.org for detailed explanations.
Basically, you need to define :
- resources : in a special section "RESOURCES"
- and projects containing tasks.

Timeframe of tasks is defined by <SCHEDULE> (beginning) and <DEADLINE> (end).
Some properties are used for :
- duration of the task
- define some task's blockers
- resources used
- and some other things

Syntax is mostly compatible with org-taskjuggler when you have renamed RESOURCES
section.

In addition, resources can also be defined as tags. I think it's better than the
org-taskjuggler property method as you can use them directly in org-mode !


My work flow
-------------------

I work for a big company with two missions :
- sysadmin (os + apps) on a 300+ server park,
- do some integration and qualification on applications,
- deploy those applications on our servers.

I am managing 15 persons in two teams. One do daily sysadmin and the other one
do the IQ and deployment part.

For the sysadmin part, it's quite straightaway : daily repetitive tasks, and little
scheduling (server installation, patch, updates…)

For the IQ / deployment team, the dates of operations are not defined by me but
others (devs for the delivery and clients for production interruption).

Scheduling is done with a long term view (6 months - 1 year)… but evolve
as dev are usually in hurry at first and in late at the end.

For this, I need to check resources allocation in order to be able to do the
work. I used ganttproject for this. But it is not really user friendly and lack
good outputs I can share with others.

org2gantt allows me to do some nice pictures for big managers. And with
org-mode, it helps me to easily keep track of tasks (notes, documents,
milestones) and who is assigned to what.
Org-mode is also really usefull keep the someday/maybe notes.
