+--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.

<tree-ish#>::
The id of the tree object(s) to be read/merged.
