This HOWTO describes good release practices for Linux and other open-source projects. By following these practices, you will make it as easy as possible for users to build your code and use it, and for other developers to understand your code and cooperate with you to improve it.

This document is a must-read for novice developers. Experienced developers should review it when they are about to release a new project. It will be revised periodically to reflect the evolution of good-practice standards.

2. Good patching practice

2.1. Do send patches, don't send whole archives or files
2.2. Send patches against the current version of the code.
2.3. Don't include patches for generated files.
2.4. Don't send patch bands that just tweak RCS or SCCS $-symbols.
2.5. Do use -c or -u format, don't use the default (-e) format
2.6. Do include documentation with your patch
2.7. Do include an explanation with your patch
2.8. Do include useful comments in your code

3. Good project- and archive- naming practice

3.1. Use GNU-style names with a stem and major.minor.patch numbering.
3.2. But respect local conventions where appropriate

6.3. Follow good C portability practices
6.4. Use autoconf/automake/autoheader
6.5. Sanity-check your code before release
6.6. Sanity-check your documentation and READMEs before release

7. Good distribution-making practice

7.1. Make sure tarballs always unpack into a single new directory
7.2. Have a README
7.3. Respect and follow standard file naming practices
7.4. Design for Upgradability
7.5. Provide RPMs

9.1. Announce to c.o.l.a and Freshmeat
