DESCRIPTION
DESCRIPTION
trees that are not directly related to the current
working tree status into a temporary index file.
trees that are not directly related to the current
working tree status into a temporary index file.
+--trivial::
+ Restrict three-way merge by `git-read-tree` to happen
+ only if there is no file-level merging required, instead
+ of resolving merge for trivial cases and leaving
+ conflicting files unresolved in the index.
+
--aggressive::
Usually a three-way merge by `git-read-tree` resolves
the merge for really trivial cases and leaves other

+--prefix=<prefix>/::
+ Keep the current index contents, and read the contents
+ of named tree-ish under directory at `<prefix>`. The
+ original index file cannot have anything at the path
+ `<prefix>` itself, and have nothing in `<prefix>/`
+ directory. Note that the `<prefix>/` value must end
+ with a slash.
+
+--exclude-per-directory=<gitignore>::
+ When running the command with `-u` and `-m` options, the
+ merge result may need to overwrite paths that are not
+ tracked in the current branch. The command usually
+ refuses to proceed with the merge to avoid losing such a
+ path. However this safety valve sometimes gets in the
+ way. For example, it often happens that the other
+ branch added a file that used to be a generated file in
+ your branch, and the safety valve triggers when you try
+ to switch to that branch after you ran `make` but before
+ running `make clean` to remove the generated file. This
+ option tells the command to read per-directory exclude
+ file (usually '.gitignore') and allows such an untracked
+ but explicitly ignored file to be overwritten.
+
+--index-output=<file>::
+ Instead of writing the results out to `$GIT_INDEX_FILE`,
+ write the resulting index in the named file. While the
+ command is operating, the original index file is locked
+ with the same mechanism as usual. The file must allow
+ to be rename(2)ed into from a temporary file that is
+ created next to the usual index file; typically this
+ means it needs to be on the same filesystem as the index
+ file itself, and you need write permission to the
+ directories the index file and index output file are
+ located in.
+

The id of the tree object(s) to be read/merged.
