Introduction
============
This repository contains code and documentation for Shimmy, a small set of
utilities designed to bring stricter POSIX® compliance to open-source operating
environments. It is designed mainly for use on Adélie Linux, but it is also
occasionally tested on Gentoo Linux, FreeBSD, OpenBSD, and Mac OS, among others.
License
```````
As the Adélie Linux project is an open-source Linux distribution, this package
is distributed under the same NCSA open source license as the distribution.
Changes

Any changes to this repository must be reviewed before being pushed to the
current branch. There are no exceptions to this rule. For security-sensitive
updates, contact the Security Team at sec-bugs@adelielinux.org.
Adding a New Utility
====================
The addition of more compliant utilities is always appreciated. If you would
like to contribute one, please ensure that:
* the utility in question is specified in IEEE Std 1003.1, 2013 Edition
(Issue 7), or Linux Standards Base Core Specification, 5.0.0;
* you have created a new directory in the top level named after the utility;
* you have included an appropriate man page for it in the directory;
* and it compiles cleanly on a strictly compliant POSIX® environment.
Note that strictly compliant POSIX® software may include shims to compile on
non-compliant systems as well - the only requirement is that they *can* be
compiled on strictly compliant systems with no changes, and that they do not
rely on unspecified interfaces or return values.
Testing
=======
You **must** test any changes on Adélie Linux. It is recommended that you
additionally test your changes on at least a glibc-based Linux distribution.
You are welcome to test on a Berkeley Software Distribution. Please note
however that they are not POSIX® compliant and may require some changes to
ensure build success.
You are additionally welcome to test on Mac OS X, Solaris, AIX, and HP-UX.
However, some of these systems deviate from POSIX® in some APIs or do not fully
implement every option. Care should be taken when testing on these systems.
Extensions
==========
Some extensions, such as BSD or GNU, can be useful in some situations. We will
review extensions on a case-by-case basis. Please do note that extensions that
directly conflict with the POSIX® specification (that is, where implementation
of said extension would cause loss of compliance with POSIX®) will never be
accepted in tree.

Legal Notice
============
POSIX® is a registered trademark of the IEEE. While we aim to provide utilities
that meet the POSIX® specification, this package has not yet been submitted to
the Open Group for testing, and thus cannot be termed as "POSIX® compliant" in
any documentation. Instead, use "POSIX® conformant".
