Zortech
Zortech Ltd was a small British software company that marketed C and C++ compilers and associated software.
The company was initially formed with the name Zorland Ltd to reflect its desire to be a direct competitor of Borland Inc. This was later changed to Zortech Ltd to avoid confusion.
Once established with a European market for their software, they created a sister company in the United States, Zortech Inc. At the same time the parent company was renamed again to Zortech International Ltd to reflects its expanded market.
The company was eventually taken over in 1991 by Symantec Inc who wanted access to their compiler technology.
The Zortech compilers are the base on which the Digital Mars compilers have been developed.
