About:
Patchutils is a suite of specialized utilities for manipulating patch files in unified diff format. It provides powerful tools like `filterdiff` to extract specific changes, `combinediff` to combine patches, and `splitdiff` to separate them. This collection is invaluable for developers needing to selectively apply, analyze, or refactor code changes from patch sets.

Key Features:

Filter patches by file name or content using regex
Combine multiple patches into a single diff
Split combined patches into individual files
Reversing and rediffing patches
Interdiff functionality to show changes between two patch versions

Use Cases:

Applying only a subset of changes from a large patch series to a codebase
Reviewing changes between different versions of a patch file
Refactoring or splitting a monolithic patch into smaller, logical commits

Alternatives:

git – Git itself has powerful diff and apply features, but patchutils offers more granular, standalone filtering and manipulation utilities specifically for patch files.
sed/awk – Standard text processing tools can manipulate diffs, but patchutils understands the diff format, making it more robust and less error-prone for this specific task.
