Within this namespace/section of the Wiki you can find many pieces of software described with additional references. If you are looking for a piece of software, the best to find it is to use this search of titles for the word 'software' .
This namespace is canonical for all pieces of software, and is intended to be used in a flat way. This means, don't bother creating sub-pages by artificial groupings that can change. For example, Software/Tools/Parsers/fooparse is just too much work to maintain.
Another namespace we can use that should be flat but provides groupings is Packages . If you want to talk about software as a group, that is the place to do it.
