README.branch --- description of branches and tags. (DRAFT)
========================================================================

Public Branches

    Current main stream of Semi-gnus development.
    Semi-gnus developers share and maintain them.

    Each public branch has a tag of the form "gnus-N1_N2" and each version
    has a tag of the form "gnus-N1_N2_N3".

    N1, N2, and N3 are changed by the following rules.

    N1 will be incremented if any fundamental architecture change is
    made.  Of cource, in this case, N2 and N3 will be reset to zero.

    N2 will be incremented (and new branch will be created) if any "major
    changes" are made.  The following cases are "major changes".
      * API changes of FLIM/SEMI(or any other modules used by Semi-gnus).
      * major version up of original Gnus.(e.g. Red/5.[34] -> Quassia/5.[56])
      * synchronization with original Gnus which requires design decision.

    N3 will be incremented if some "minor changes" are made.  The follwoing
    cases are "minor changes".
      * small bug fix.
      * synchronization with original Gnus without design decision.

    The following branch tags are currently available.

	for-semi-1_5	Semi-gnus for SEMI 1.5 API
	for-semi-1_6	Semi-gnus for SEMI 1.6 API
	gnus-6_5	Semi-gnus for SEMI 1.7 API
	gnus-6_6	Semi-gnus for SEMI 1.8, FLIM 1.7 API (stable)
	gnus-6_7	Semi-gnus for SEMI 1.8, FLIM 1.7 API (develop)
	gnus-6_8	Semi-gnus for SEMI 1.8, FLIM 1.8 or 1.9 API


The Vendor Branch

    Original version of Gnus.
    Each version has a tag of the form "qgnus-0_XY" or "gnus-5_X_Y".

    The branch tag for the vendor branch is "larsi".


The Main Trunk

    Semi-gnus was developed on the main trunk until current branch-
    management plan (See "Public Branches" above) was introduced.
    Now the main trunk is used only for the root of branches --- when
    creating new branches, current develop branch is merged back to the
    main trunk and new branches are created from there.

    Each version has a tag of the form "gnus-6_N2_N3" (0 < N2 < 5) or
    "semi-gnus-6_N2_N3" (N2 > ??).


"semi-gnus" Tag

    Assigned to the latest stable version. (on the main trunk???)


"for-semi-N1_N2" Tags

    Were assigned to corresponding version of SEMI API N1.N2.
    We don't use this convention now.


Private Branches

    Some Semi-gnus developers have their own "private branches".
    Each private branch may have its own goal and/or policy.
    See README.${tag} (if exists) for information of each branch.

    The following branch tags are curretly available.

	akr		Owner: Tanaka Akira
	himi		Owner: Miyashita Hisashi
	ichikawa	Codename: T-gnus, Owner: Tatsuya Ichikawa
	shuhei-k	Codename: Shoe-gnus, Owner: Shuhei KOBAYASHI
