+HOW MERGE WORKS
+---------------
+
+A merge is always between the current `HEAD` and one or more
+remote branch heads, and the index file must exactly match the
+tree of `HEAD` commit (i.e. the contents of the last commit) when
+it happens. In other words, `git-diff --cached HEAD` must
+report no changes.
+
+[NOTE]
+This is a bit of lie. In certain special cases, your index are
+allowed to be different from the tree of `HEAD` commit. The most
+notable case is when your `HEAD` commit is already ahead of what
+is being merged, in which case your index can have arbitrary
+difference from your `HEAD` commit. Otherwise, your index entries
+are allowed have differences from your `HEAD` commit that match
+the result of trivial merge (e.g. you received the same patch
+from external source to produce the same result as what you are
+merging). For example, if a path did not exist in the common
+ancestor and your head commit but exists in the tree you are
+merging into your repository, and if you already happen to have
+that path exactly in your index, the merge does not have to
+fail.
+
+Otherwise, merge will refuse to do any harm to your repository
+(that is, it may fetch the objects from remote, and it may even
+update the local branch used to keep track of the remote branch
+with `git pull remote rbranch:lbranch`, but your working tree,
+`.git/HEAD` pointer and index file are left intact).
+
+You may have local modifications in the working tree files. In
+other words, `git-diff` is allowed to report changes.
+However, the merge uses your working tree as the working area,
+and in order to prevent the merge operation from losing such
+changes, it makes sure that they do not interfere with the
+merge. Those complex tables in read-tree documentation define
+what it means for a path to "interfere with the merge". And if
+your local modifications interfere with the merge, again, it
+stops before touching anything.
+
+So in the above two "failed merge" case, you do not have to
+worry about lossage of data --- you simply were not ready to do
+a merge, so no merge happened at all. You may want to finish
+whatever you were in the middle of doing, and retry the same
+pull after you are done and ready.
+
+When things cleanly merge, these things happen:
+
+1. the results are updated both in the index file and in your
+ working tree,
+2. index file is written out as a tree,
+3. the tree gets committed, and
+4. the `HEAD` pointer gets advanced.
+
+Because of 2., we require that the original state of the index
+file to match exactly the current `HEAD` commit; otherwise we
+will write out your local changes already registered in your
+index file along with the merge result, which is not good.
+Because 1. involves only the paths different between your
+branch and the remote branch you are pulling from during the
+merge (which is typically a fraction of the whole tree), you can
+have local modifications in your working tree as long as they do
+not overlap with what the merge updates.
+
+When there are conflicts, these things happen:
+
+1. `HEAD` stays the same.
+
+2. Cleanly merged paths are updated both in the index file and
+ in your working tree.
+
+3. For conflicting paths, the index file records up to three
+ versions; stage1 stores the version from the common ancestor,
+ stage2 from `HEAD`, and stage3 from the remote branch (you
+ can inspect the stages with `git-ls-files -u`). The working
+ tree files have the result of "merge" program; i.e. 3-way
+ merge result with familiar conflict markers `<<< === >>>`.
+
+4. No other changes are done. In particular, the local
+ modifications you had before you started merge will stay the
+ same and the index entries for them stay as they were,
+ i.e. matching `HEAD`.
+
+After seeing a conflict, you can do two things:
+
+ * Decide not to merge. The only clean-up you need are to reset
+ the index file to the `HEAD` commit to reverse 2. and to clean
+ up working tree changes made by 2. and 3.; `git-reset` can
+ be used for this.
+
+ * Resolve the conflicts. `git-diff` would report only the
+ conflicting paths because of the above 2. and 3.. Edit the
+ working tree files into a desirable shape, `git-update-index`
+ them, to make the index file contain what the merge result
+ should be, and run `git-commit` to commit the result.
+

DESCRIPTION
-----------
This script is used to move or rename a file, directory or symlink.
In the first form, it renames <source>, which must exist and be either
-a file, symlink or directory, to <destination>, which must not exist.
+a file, symlink or directory, to <destination>.
In the second form, the last argument has to be an existing
directory; the given sources will be moved into this directory.
OPTIONS
-------
-f::
- Force renaming or moving even targets exist
+ Force renaming or moving of a file even if the target exists
-k::
Skip move or rename actions which would lead to an error
condition. An error happens when a source is neither existing nor
OPTIONS
-------
-m::
- Perform a merge, not just a read.
+ Perform a merge, not just a read. The command will
+ refuse to run if your index file has unmerged entries,
+ indicating that you have not finished previous merge you
+ started.
--reset::
-
- Same as -m except that unmerged entries will be silently ignored.
+ Same as -m, except that unmerged entries are discarded
+ instead of failing.
-u::
After a successful merge, update the files in the work
trees that are not directly related to the current
working tree status into a temporary index file.
-
<tree-ish#>::
The id of the tree object(s) to be read/merged.

regex. It can be used with -m to also see the default regexes.
You must escape forward slashes.
--l <max_num_changes>::
- Limit the number of SVN changesets we pull before quitting.
- This option is necessary because the SVN library has serious memory
- leaks; the recommended value for nontrivial imports is 100.
+-l <max_rev>::
+ Specify a maximum revision number to pull.
- git-svnimport will still exit with a zero exit code. You can check
- the size of the file ".git/svn2git" to determine whether to call
- the importer again.
+ Formerly, this option controlled how many revisions to pull, due to
+ SVN memory leaks. (These have been worked around.)
-v::
Verbosity: let 'svnimport' report what it is doing.
