Macromedia is to buy San Diego-based help authoring firm, eHelp Corporation, for $65m (£38m).
EHelp's offerings include automated end-user help application, RoboHelp, and a Flash-based software demonstration product, RoboDemo. Both are used to create content such as help systems and software simulations.
By combining this software with the Macromedia authoring tool and Macromedia Breeze tools, developers will be able to create user assistance and tutorial content to support their core applications, Macromedia said.
Rob Burgess, Macromedia's chairman and chief executive, said: "eHelp defined the help authoring space with RoboHelp and is now ushering in a new generation of demonstration software with RoboDemo.
"We look forward to nurturing eHelp's thriving business and continuing this tradition of innovation."
