+SPLITTING COMMITS
+-----------------
+
+In interactive mode, you can mark commits with the action "edit".  However,
+this does not necessarily mean that 'git rebase' expects the result of this
+edit to be exactly one commit.  Indeed, you can undo the commit, or you can
+add other commits.  This can be used to split a commit into two:
+
+- Start an interactive rebase with 'git rebase -i <commit>^', where
+  <commit> is the commit you want to split.  In fact, any commit range
+  will do, as long as it contains that commit.
+
+- Mark the commit you want to split with the action "edit".
+
+- When it comes to editing that commit, execute 'git reset HEAD^'.  The
+  effect is that the HEAD is rewound by one, and the index follows suit.
+  However, the working tree stays the same.
+
+- Now add the changes to the index that you want to have in the first
+  commit.  You can use gitlink:git-add[1] (possibly interactively) and/or
+  gitlink:git-gui[1] to do that.
+
+- Commit the now-current index with whatever commit message is appropriate
+  now.
+
+- Repeat the last two steps until your working tree is clean.
+
+- Continue the rebase with 'git rebase --continue'.
+
+If you are not absolutely sure that the intermediate revisions are
+consistent (they compile, pass the testsuite, etc.) you should use
+gitlink:git-stash[1] to stash away the not-yet-committed changes
+after each commit, test, and amend the commit if fixes are necessary.

+
+Running 'git-merge' or 'git-pull' is NOT recommended on a branch you
+plan to dcommit from.  Subversion does not represent merges in any
+reasonable or useful fashion; so users using Subversion cannot see any
+merges you've made.  Furthermore, if you merge or pull from a git branch
+that is a mirror of an SVN branch, dcommit may commit to the wrong
+branch.
+
+'git-clone' does not clone branches under the refs/remotes/ hierarchy or
+any git-svn metadata, or config.  So repositories created and managed with
+using git-svn should use rsync(1) for cloning, if cloning is to be done
+at all.
+
+Since 'dcommit' uses rebase internally, any git branches you git-push to
+before dcommit on will require forcing an overwrite of the existing ref
+on the remote repository.  This is generally considered bad practice,
+see the git-push(1) documentation for details.
+
+Do not use the --amend option of git-commit(1) on a change you've
+already dcommitted.  It is considered bad practice to --amend commits
+you've already pushed to a remote repository for other users, and
+dcommit with SVN is analogous to that.

 -------------------------------------------------
 
-The next question is where to put these exclude patterns so that git can
-find them. Git looks for exclude patterns in the following files:
+See gitlink:gitignore[5] for a detailed explanation of the syntax.  You can
+also place .gitignore files in other directories in your working tree, and they
+will apply to those directories and their subdirectories.  The `.gitignore`
+files can be added to your repository like any other files (just run `git add
+.gitignore` and `git commit`, as usual), which is convenient when the exclude
+patterns (such as patterns matching build output files) would also make sense
+for other users who clone your repository.
 
-`.gitignore` files in your working tree:::
-	   You may store multiple `.gitignore` files at various locations in your
-	   working tree. Each `.gitignore` file is applied to the directory where
-	   it's located, including its subdirectories. Furthermore, the
-	   `.gitignore` files can be tracked like any other files in your working
-	   tree; just do a "`git add .gitignore`" and commit. `.gitignore` is
-	   therefore the right place to put exclude patterns that are meant to
-	   be shared between all project participants, such as build output files
-	   (e.g. `\*.o`), etc.
-`.git/info/exclude` in your repo:::
-	   Exclude patterns in this file are applied to the working tree as a
-	   whole. Since the file is not located in your working tree, it does
-	   not follow push/pull/clone like `.gitignore` can do. This is therefore
-	   the place to put exclude patterns that are local to your copy of the
-	   repo (i.e. 'not' shared between project participants), such as
-	   temporary backup files made by your editor (e.g. `\*~`), etc.
-The file specified by the `core.excludesfile` config directive:::
-	   By setting the `core.excludesfile` config directive you can tell git
-	   where to find more exclude patterns (see gitlink:git-config[1] for
-	   more information on configuration options). This config directive
-	   can be set in the per-repo `.git/config` file, in which case the
-	   exclude patterns will apply to that repo only. Alternatively, you
-	   can set the directive in the global `~/.gitconfig` file to apply
-	   the exclude pattern to all your git repos. As with the above
-	   `.git/info/exclude` (and, indeed, with git config directives in
-	   general), this directive does not follow push/pull/clone, but remain
-	   local to your repo(s).
-
-[NOTE]
-In addition to the above alternatives, there are git commands that can take
-exclude patterns directly on the command line. See gitlink:git-ls-files[1]
-for an example of this.
+If you wish the exclude patterns to affect only certain repositories
+(instead of every repository for a given project), you may instead put
+them in a file in your repository named .git/info/exclude, or in any file
+specified by the `core.excludesfile` configuration variable.  Some git
+commands can also take exclude patterns directly on the command line.
