Build, version and package naming convention

As there are more and more distributions, we need more consistency to name
build and version. Here is a proposal inspired from the eclipse project.

Nuxeo build types
=====================

• Integration Builds

They are nightly builds that pass all integration tests. Integration
builds may be promoted to stable builds after a few days of testing

• Stable Builds

Stable builds are integration builds that have been found to be stable
enough for most developers to use. They are milestones or release candidates.

• Releases

Releases are builds that have been declared major releases, Releases are
the right builds for people who want to be on a stable, tested release,
and don't need the latest features and improvements.

• Maintenance releases

Maintenance builds are produced to incorporate fixes into an existing
release.

Nuxeo build versionning
========================

• Integration Builds (5.1.7-I20090225_1730)

The version used are target release (5.1.7 or 5.2.0), an 'I' for
integration and a time stamp like 5.1.7-I20090225_1730, all the jar inside
the package are also using this versions.

• Stable Builds (5.1.7-RC2)

Version are using a M for milestone or RC for release candidate
ex: 5.1.7-M2 or 5.1.7-RC1.

• Releases (5.1.7)

Releases are builds that have been declared major releases, Releases are
the right builds for people who want to be on a stable, tested release,
and don't need the latest features and improvements.

Version is 5.1.7 or 5.2.0 without any final or GA.

• Maintenance releases (5.1.7.1)

Maintenance builds are produced to incorporate fixes into an existing
release, we just add a number to the release version: 5.1.7.2

Nuxeo build distribution naming
==================================

• projects:

• Nuxeo EP: nuxeo-ep
• Nuxeo Web Engine: nuxeo-we
• Nuxeo shell: nuxeo-shell

• versions (see above section)

• web server

• JBoss: jboss
• Jetty: jetty
• Glassfish: gf

• arch

• windows 32b: win32
• windows 64b: win32-x86_64

• package release number, a number that is incremented until expected stuff
  is packaged.

• extension type:

• windows: .exe
• unix: .tar.gz
• java: .jar
• zip: .zip

Exemples:

• nuxeo-ep-5.2.0-jboss-1.zip
• nuxeo-ep-5.2.0-M4-jboss-1.zip
• nuxeo-we-5.2.0-I20090225_1200-jetty-1.zip
• nuxeo-ep-5.2.0-I20090225_1200-jboss-win32-x86_64-1.exe
