Why
For quite a while now I've been struggling to find a simple project management, task scheduling and progress tracking tool for a small team to easily collaborate. While things like Microsoft Project, OpenProj and Project.NET have their uses, I found them to be just too complex and cumbersome to use, for what was essentially a simple graph topological sort with a few bells and whistles on the side. Being finally fed up this weekend with having to type ordered lists in Wiki, I've decided to build a tool that suits my needs.

What
EzPlan allows you to:


 * Create task hierarchies
 * Specify out-of-hierarchy dependencies between the tasks
 * EzPlan will warn you if you end up with loops in your topology
 * Render different types of views for the created task hierarchies

Usage
Writing your own EzPlan consists of two steps:
 * 1) Define a plan
 * 2) Render a view of the plan

Defining an EzPlan
A simple EzPlan looks something like this: 
 * 1) [assigned="arcivanov"]Decide to build EzPlan
 * 2) [completed="1"]Evaluate MS Project
 * 3) Evaluate OpenProj
 * 4) [completed="1"]Observe multiple crashes
 * 5) Evaluate Project.NET

trying to force Project.NET to recalculate workspace progress. 
 * 1) [completed="1" weight="3" id="ora"]Install Oracle DB
 * 2) [completed="1" id="mq"]Install Apache MQ
 * 3) [completed="50%" depends="ora,mq"]Bang your head on the table repeatedly

So I defined a plan. Now what?
Now you insert tags to create reports like this:  or like this:  or like this: 

What do reports look like?
The definition view looks exactly like report in the Defining an EzPlan section.

Task view report looks this:

Dependency view report with absolute weighting looks this:
