+*** README.developers - JACK development practices                  ***
+=======================================================================
+
+Version: $id$
+
+-----------------------------------------------------------------------
+ What is this? 
+-----------------------------------------------------------------------
+
+This file is a collection of practices and rules for JACK
+development. If you have questions, or would like to make 
+changes, raise the issue on jackit-devel (see 
+http://jackit.sourceforge.net/lists ).
+
+-----------------------------------------------------------------------
+ Version numbers 
+-----------------------------------------------------------------------
+
+1. JACK's package version
+
+JACK's package version is set in configure.in, and consists of 
+major, minor and revision numbers. This version should be 
+updated whenever a non-trivial set of changes is committed 
+to CVS:
+ 
+   major version = ask on jackit-devel :)
+   minor version = incremented when any of the public or internal
+                   interfaces are changed
+   revision      = incremented when implementation-only
+                   changes are made
+
+2. Client API versioning
+ 
+JACK clients are affected by two interfaces, the JACK Client API (libjack)
+and the JACK Client Protocol API (interface between jackd and 
+libjack). The former one is versioned using libtool interface 
+versioniong (set in configure.in). This version should be updated 
+whenever a set of changes affecting the interface is committed 
+to CVS:
+
+    current  = incremented whenever the public libjack API is changed 
+    revision = incremented when the libjack implementation is changed
+    age      = current libjack is both source and binary compatible with
+               libjack interfaces current,current-1,...,current-age
+
+Note! All changes that affect the libjack API must be documented 
+in jack/libjack/ChangeLog using the standard ChangeLog style
+(see GNU developer docs).
+
+---------------------------------------------------------------------
+ Sending patches
+-----------------------------------------------------------------------
+
+1. People without CVS-access
+
+Send your patches to jackit-devel. Normally patches are accepted
+by Paul Davis. He either applies the patch right away, or 
+sends an "ok to me" message, after which other developers with
+CVS-access can commit the patch.
+
+2. People with CVS-access
+
+Trivial changes can be committed without review. For non-trivial 
+changes, you should first send a proposal to jackit-devel and
+wait for comments. There are no strict approval rules so use of
+common sense is recommended. ;)
+
+3. Tips for making patches
+
+- test your patch on a clean CVS-checkout
+- remember to run cvs update before making commits
+
+-----------------------------------------------------------------------
+ CVS Access
+-----------------------------------------------------------------------
+
+TBD
+
+---------------------------------------------------------------------
+ Uses of external libraries and other packages
+-----------------------------------------------------------------------
+
+The main JACK components, jackd and libjack, should only use 
+standard POSIX and ANSI-C services. Other components like
+example clients and drivers, may rely on other packages, but 
+these dependencies should not affect the main build process.
