NAME
       git-write-tree - Create a tree object from the current index

SYNOPSIS
       git write-tree [--missing-ok] [--prefix=<prefix>/]

DESCRIPTION
       Creates a tree object using the current index. The name of the new tree object is printed to standard output.

       The index must be in a fully merged state.

       Conceptually, git write-tree sync()s the current index contents into a set of tree files. In order to have that match what is actually in
       your directory right now, you need to have done a git update-index phase before you did the git write-tree.

OPTIONS
       --missing-ok
	   Normally git write-tree ensures that the objects referenced by the directory exist in the object database. This option disables this
	   check.

       --prefix=<prefix>/
	   Writes a tree object that represents a subdirectory <prefix>. This can be used to write the tree object for a subproject that is in the
	   named subdirectory.
