Into these:
http://www.globulation2.org/wiki/Download_and_Install_new
http://www.globulation2.org/wiki/Compiling
http://www.globulation2.org/wiki/Packages
Given the definition of the word download ("tranfer of data" -
http://en.wikipedia.org/wiki/Download) I think the following breakdown
would make more sense:
wiki/Downloads
subsection: prebuilt packages
subsections for each OS/package type
subsection: source - list of places where to get the source
wiki/Installation
a section for each OS
a short section for quick compilation instructions or a link to a
development section about compilation
I think the above resembles what is commonly done in other free
software projects. For example:
http://www.blender.org/download/get-blender/
http://download.openoffice.org/
http://audacity.sourceforge.net/download/
