# pds/skeleton

This publication describes a standard filesystem skeleton suitable for all PHP
packages.

Please see <https://github.com/php-pds/skeleton_research> for background
information.

Command-line tools for `validating` or `generating` PDS conform packages which are included with this standard are documented [here](./docs/tools.md).

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this publication are to be
interpreted as described in [RFC 2119](http://tools.ietf.org/html/rfc2119).

## Summary

A package MUST use these names for these root-level directories:

| If a package has a root-level directory for ... | ... then it MUST be named: |
| ----------------------------------------------- | -------------------------- |
| command-line executables                        | `bin/`                     |
| configuration files                             | `config/`                  |
| documentation files                             | `docs/`                    |
| web server files                                | `public/`                  |
| other resource files                            | `resources/`               |
| PHP source code                                 | `src/`                     |
| test code                                       | `tests/`                   |

A package MUST use these names for these root-level files:

| If a package has a root-level file for ...      | ... then it MUST be named: |
| ----------------------------------------------- | -------------------------- |
| a log of changes between releases               | `CHANGELOG(.*)`            |
| guidelines for contributors                     | `CONTRIBUTING(.*)`         |
| licensing information                           | `LICENSE(.*)`              |
| information about the package itself            | `README(.*)`               |

A package SHOULD include a root-level file indicating the licensing and
copyright terms of the package contents.
