If you find that a wiki is incorrect, please please please take the time
to fit it! That's the whole point of a wiki and the best way to stop
garbage being propagated. A few minutes spent there removing/fixing

countless mop-up jobs and substandard softwares for hundreds of end-users.

debate & justifications can be listed on the entry's "Discussion" page.
