+- The guile-core tree is now versioned similarly to the Linux kernel.
+Guile now always uses three numbers to represent the version,
+i.e. "1.6.5".  The first number, 1, is the major version number, the
+second number, 6, is the minor version number, and the third number,
+5, is the micro version number.  Changes in major version number
+indicate major changes in Guile.
+
+Minor version numbers that are even denote stable releases, and odd
+minor version numbers denote development versions (which may be
+unstable).  The micro version number indicates a minor sub-revision of
+a given MAJOR.MINOR release.
+
+- A default CVS checkout will get the current unstable development
+tree.  However, for each stable release, a CVS branch is created so
+that release (and ongoing maintenance) of the stable version can
+proceed independent of the development of the next unstable version.
+To check out a particular stable branch, you just need to specify "-r
+branch_release-X-Y" to your CVS checkout command (or to any update).
+For example, if you wanted to check out the 1.6 stable branch, you
+would specify "-r branch_release-1-6".
+
+So, for example, during a normal development cycle, work will proceed
+on an unstable version, say 1.5.X, until it is decided that it's time
+for a stable release.  At that point, a branch named
+branch_release-1-6 will be created, and the version numbers on the
+HEAD of the CVS tree (the trunk, i.e. what you get by default), will
+be changed to reflect the new unstable version 1.7.X.  Then unstable
+development will proceed on the unstable version, while the stable
+1.5.X branch is fixed up for the eventual 1.6.0 release.
+
+Anytime you want to yank an existing checked out tree to the stable
+branch, you can run a command like this:
+
+  cvs -z3 update -r branch_release-1-6 -Pd
+
+This will yank the working directory over on to the stable release
+branch.  Note that this directory will track that branch from then on
+unless you do something to yank it back to the main (unstable) trunk.
+
+To go back to the unstable branch, you can use
+
+  cvs -z3 update -A -Pd
+
+Note that in either case, you should probably make sure you've
+commited or removed all local changes before running the commands or
+you're likely to have some unexpected results.
+
+Finally note that one approach, should you need to work on both
+branches, is to keep two trees checked out, one stable, the other
+unstable and you can work in whichever is appropriate.
+
+To save some initial bandwidth, you can check out either the stable
+tree or the unstable tree, and then do something like this:
+
+  cp -a core-unstable core-1.5
+  cd core-1.5
+  cvs -z3 update -r branch_release-1-6 -Pd
+
+- The stable and unstable CVS trees are distinct, and no changes will
+automatically propagate between them.  If you make changes that need
+to show up both places, you'll need to apply the changes both places.
+You *might* be able to do this with a cvs command, but often you'll
+probably need to apply the changes by hand or risk migrating
+superfluous modifications between the two versions.  This is
+particularly important when moving a change from the unstable branch
+to the stable branch.
+
+- In general, please don't be adventurous with the stable branch.  We
+mostly want bugfixes, documentation improvements, build improvements,
+etc., though exceptions will doubtless exist.
+
+- There are a few CVS tagging conventions which follow the Scheme
+convention that dashes are used to separate words within a single
+symbol, and so dashes bind more tightly than underscores.  This means
+that foo-bar_baz-bax indicates that foo-bar is somehow separate from
+baz-bax.  The conventions are as follows:
+
+  Branch root tags:
+  -----------------
+  anytime just before you create a branch it's a good
+  idea to create a normal tag so that you can refer to the branch point
+  on the main trunk as well as on the branch.  So please use a tag of
+  the form
+
+    branch-root-release-1-X
+
+  or more generally, for other non-release branches:
+
+    branch-root_FOO
+
+  Branch tags:
+  ------------
+  for the branch tag itself please use
+
+   branch_release-1-6
+
+  or more generally, for other non-release branches:
+
+    branch_FOO
+
+  Merge tags:
+  -----------
+  Whenever you're merging a branch back into the trunk (or into another
+  branch repeatedly) you need to tag the branch each time you merge.  If
+  you don't do that, you won't be able to merge repeatedly without
+  possibly tedious conflicts.  For those tags, we suggest:
+
+    branch-merge_SOME-FOO_to_SOME-BAR_1
+    branch-merge_SOME-FOO_to_SOME-BAR_2
+    ..
+
+  As an example, SOME-BAR might be trunk, or even perhaps another branch
+  like branch-mvo-super-fixes :>
+
+  More mundanely, you might have
+
+    branch-merge_release-1-6_to_trunk_1
+
+  (Merging the stable branch to the trunk like this
+   will probably be much more common, when it happens, than the
+   reverse for the reasons mentioned above.
+
+  Release tags:
+  -------------
+  When releasing a new version of guile, please use:
+
+    release_X-Y-Z
+
+  i.e.
+
+    release_1-6-0
+
+- If you hack on a stable branch, please apply any relevant patches or
+fixes to the current unstable version (the main CVS trunk) as well.
+Similarly, please back-port any important fixes to the unstable CVS
+tree to the current stable branch.
