## Description

git-sizer is a repository size analyzer and auditing tool used to calculate the size of Git objects, references, and commit histories. It functions as a blob and commit auditor, a history depth profiler, and a checkout weight calculator to identify performance bottlenecks within a Git store.

The tool identifies oversized files and bloated commits to assist with repository maintenance and storage analysis. It detects large objects and measures the depth of commit chains and annotated tags to analyze repository complexity and bloat.

The software covers version control auditing and performance optimization by measuring the potential disk space and path depth required for a full working copy checkout. It employs a mechanism to flag components that exceed size limits and analyzes the impact of large objects on development operations.
