Create a fully-functional mini-application called 'TechLog' which is a personal technical blog management system. This application will allow users to manage their technical blogs by adding new posts, editing existing ones, deleting old posts, and searching through past entries. TechLog will also include a feature to categorize posts into different tags such as 'Python', 'Machine Learning', 'Web Development', etc., making it easier for users to organize their content.

The application should have a user-friendly command-line interface where users can interact with the system using simple commands. Users should be able to:
- Add new blog posts with title, content, and tags.
- Edit existing blog posts by updating any of the fields (title, content, tags).
- Delete blog posts by specifying the post ID.
- Search for blog posts by keywords or tags.
- List all available tags.

To make the application more robust, implement functionality to save the blog data to a local file or database so that it persists even after the application is closed. Additionally, consider adding features like version control for posts, allowing users to revert changes if needed.

The '20206205tech-python-common' package is designed to simplify common development tasks in Python. In this project, you will utilize its core functionalities to handle file operations, manage configurations, and provide utilities for logging and error handling. Specifically, use the file handling functions provided by the package to read/write blog data to/from a file. Utilize configuration management features to store settings like file paths and logging levels. Leverage the logging utilities to track important events and errors within the application.

Your goal is to demonstrate how the '20206205tech-python-common' package can be integrated into a real-world application to enhance its capabilities and ease of development.
