This is an example software package website. Just copy the softwaresite subdirectory into your wiki to quickly produce a website for a piece of software.
Some additional configuration you might want to do:
Make sure to configure ikiwiki to generate RSS or Atom feeds.
The softwaresite/doc subdirectory is intended to hold docs about your software package. These docs can be included in the package itself; there is a Makefile that will use ikiwiki to build static html documentation from the docs directory. ikiwiki itself uses a similar system to build its documentation.
