EC Software
EC Software was originally founded in 1993 and went a long way from the initial small one-man shop for point-of-sale software to the documentation tools specialist that it is today. With the first release of Help and Manual in 1997 the company changed its business focus to documentation software and developer tools. Today, Help and Manual is one of the best selling and most popular help authoring tools world-wide.
