Limited Features
As a lightweight tool, GPP may lack some advanced features present in more comprehensive preprocessing solutions, potentially limiting its applicability for complex tasks.
Niche Usage
GPP is specifically designed for text preprocessing tasks, which means it may not be suitable for users looking for a broader range of functionalities.
Documentation
Documentation and community support for GPP might not be as extensive as for more popular alternatives, which can be a hindrance for new users.

Portability
GNU M4 is highly portable and can run on almost any Unix-like operating system, which makes it versatile for various environments.
Macro Capabilities
It offers powerful macro processing features that are useful for a wide range of text processing tasks, such as configuring scripts, code generation, and templating.
Simplicity
M4 is relatively simple to use for basic macro processing tasks, which makes it accessible to new users and suitable for straightforward applications.
Integration
GNU M4 often integrates well with other tools and scripts, making it a useful component in build systems and automated workflows.

Limited Built-in Functions
Compared to more modern scripting languages, M4 lacks a wide range of built-in functions and features, which may limit its use for more complex tasks.
Steep Learning Curve
While simple tasks are easy to set up, mastering M4 for more advanced uses can require a deeper understanding of its syntax and capabilities.
Debugging Difficulty
Debugging macros in M4 can be challenging, especially for large scripts, due to the lack of advanced debugging tools and support.
Performance Considerations
For very large and complex scripts, performance may become an issue, as M4 is not optimized for handling large-scale data manipulation compared to more modern alternatives.
