## What it is
The C Code Archive Network (CCAN) is a collection of reusable C modules, analogous to CPAN for Perl, distributed as self-contained directories that can be dropped into projects. It includes helper tools for creating and managing module trees.

## Use cases
- find reusable C modules for my project
- add ccan modules to a C codebase
- avoid rewriting common C utilities
- browse a network of C code packages
- create a ccan tree for my build

## When to choose
- you write C and want small, self-contained, copy-in modules
- you need battle-tested utility code without heavy dependencies
- you want a CPAN-like ecosystem for C

## When to avoid
- you need a package manager with dependency resolution rather than vendored source modules
- you work in a language other than C
- you require formally licensed or maintained releases (repo has no license file)

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools, cli, build-tool
- domain: developer-tools, programming-languages, cross-platform
- platform: c, cross-platform, cli
- tags: c-modules, code-archive, reusable-components, cpkg, linux
