Added detailed features list section taken directly from the text and added direct binary and source links. Unlike SMMU, there seems no mention of restriction on linking to these, but if this poses a problem, then those links can be removed.
'''sfdoom''' is a [[source port]] created by [[Simon Howard (Fraggle)]] which was a forerunner of [[SMMU]]. It was derived from [[DOSDoom]] by [[Chi Hoang]]. It contained several features that would later be rewritten in SMMU, including a [[console]], colored lighting, start map, and basic scripting. SMMU, though not directly derived from sfdoom, was intended as a rewrite of the project, and started out initially with the same name as its forerunner.
