About M4
M4 was developed in the late 1970s as a part of the Unix operating system. It evolved from earlier macro processors and was designed to provide a more powerful and flexible tool for text processing and automation tasks within Unix.
Strengths of M4 include its simplicity, flexibility, and powerful macro capabilities. Weaknesses involve its limited error handling and debugging features. Competitors include other macro processors like CPP (C Preprocessor) and more modern templating engines such as Jinja2 and Mustache.
