<section title="Branching Conventions">
<p>
Branches are tagged in the following way:
</p>
<ul>
<li>REL_1_5_BRANCH</li>
<li>REL_2_0_BRANCH</li>
</ul>
<p>
Merge points should be tagged as follows:
</p>
<ul>
<li>REL_1_5_BRANCH_MERGE1</li>
<li>REL_1_5_BRANCH_MERGE2</li>
<li>etc...</li>
</ul>
<p>
Releases should be tagged as:
</p>
<ul>
<li>REL_1_5</li>
<li>REL_1_5_1</li>
<li>REL_1_5_2</li>
<li>etc...</li>
</ul>
</section>
<section title="Branching Advise">
<p>
Don't forget which branch you are currently on. This is critically
important. Committing stuff to the wrong branch causes all sorts of
headaches. Best to name your checkout after the branch you are on.
</p>
</section>
<section title="Who Manages Branching?">
<p>
All branching is currently managed by Glen Stampoultzis. If you wish
to create your own branch please let him know. Merging is also
handled by Glen. Just pop him a mail if you feel it's necessary to
create a branch or perform a merge.
</p>
<p>
The reason to go through a single point for branching is that it can be
an easy thing to get wrong. Having a single person managing branches
means there is less chance of getting getting our wires crossed with this
difficult area of CVS.
</p>
</section>
<section title="Currently Active Branches">
<p>
The following branches are currently active:
</p>
<table>
<tr>
<th>
<b>Branch</b>
</th>
<th>
<b>Description</b>
</th>
</tr>
<tr>
<td>
HEAD
</td>
<td>
This is the trunk and is always active. Currently it is being used to continue development
of the 2.0 release.
</td>
</tr>
<tr>
<td>
REL_1_5_BRANCH
</td>
<td>
All bug fixes not specifically relevant to the 2.0 work should be placed in this branch.
From here they will merged back to the trunk and the merge point marked.
