CVS, GIT, and Mercurial as well as other well-known version control systems cannot version directories. In other words, you cannot add empty directories. A "workaround" for this issue is to use placeholder files that are placed into empty directories. These placeholder files can then be committed into the repository and will make sure that, upon checkout, the directory tree is entirely reconstructed. The problem with using placeholder files is that you need to create them, and need to delete them if they are not necessary anymore (because sub-directories or real files were added). With big source trees, managing these placeholder files can be cumbersome and error prone. MarkEmptyDirs can manage the creation/deletion of such placeholder files automatically. It creates placeholder files in all empty "leaf" directories. If later on new files or directories are put into such directories, the placeholder files are not necessary anymore, and are removed automatically.

Sustainable IDE (SIDE) is a set of graphical tools for developers who want to build sustainable software. Sustainable software is software you can extend easily, from a functional or technological point of view. On one hand, this means that when a user has a new requirement, it's easy for any developer to add it, even if the original author is not there anymore. On another hand, if you want to change the underlying technologies, you don't need to rewrite your existing application from scratch. Sustainable Software gives you the freedom to change technology, requirements, or achitecture. This can be achieved thanks to the use of models in a model driven software development (MDSD) paradigm.
