The purpose of this template is to work around copying and pasting the same list of related articles, and removing the page itself from the list.
This template works by using the #switchparser function, allowing users to add a specific parameter value to the template parameter, and create the result on the template. By calculation, the template then works out which of the listed articles should be excluded (the page itself), no fuss necessary.
To use, add the following code to the location where the "See Also" section would normally appear on an article:

NB: Please use the exact spelling as it appears in the parameters list: any variation will cause no list to be generated on the article.
