-NAME
-----
-git-freeze - Freeze all changes on a branch (indexed and unindexed)
-
-SYNOPSIS
---------
-[verse]
-'git freeze'
-
-DESCRIPTION
------------
-
-`git freeze` works a lot like `git stash`, in that it stores the current changes
-in your working copy and index 'somewhere'. Unlike `git stash`, `git freeze`
-stores those changes on your current branch. This effectively allows you to
-'pause' development of a branch, work on something else, and then come back to
-exactly the same working state later (by running `git thaw`).
-
-`git freeze` will make up to 2 commits on your branch. A commit with the message
-`FREEZE.indexed` will contain all changes which you’ve added to your index (like
-with 'git add', 'git mv', 'git rm', etc.). A commit with the message
-`FREEZE.unindexed` will contain all changes which were not in your index at the
-time you ran git freeze (freshly modified files, new files, etc.).
