Ellié Computing wants to encourage Open Source projects. We offer free licences or significant rebates to active contributors of free projects, or multi-licensed projects from which one at least is free.
Here are the steps to follow to get ECMerge licences:
actively participate to an Open Source project (developer in charge of the project or numerous patches...)
add the following text in your "Credits" or "Contributions" page: Ellié Computing contributes to this project by giving free licences of ECMerge, comparison/merge tool.
contact us by email with a description of your role in the Open Source Project and the URL of the page containing the reference to ECMerge.
ECMerge can be configured as the default diff/merge tool to use with your version control system (CVS, SVN or any other). Please look at this page to get the procedure to integrate ECMerge into your source code control software.
git (http://git.or.cz): a distributed VCS, with support to use ECMerge as its diff/merge tool
