Simeon (email client)

Simeon was an early email client developed at the University of California, Berkeley in the late 1970s and early 1980s. It ran on Unix systems and was notable for its command-line interface and extensibility through Lisp. Simeon was designed to be a powerful and customizable tool for managing email, allowing users to tailor the program to their specific needs. It was influential in the development of later email clients, particularly those emphasizing flexibility and scripting capabilities. Key features included support for multiple mailboxes, powerful searching and filtering capabilities, and the ability to define custom commands using Lisp. Though not widely used today, Simeon represents an important stage in the evolution of email client software.
