--allow-binary-replacement::
When applying a patch, which is a git-enhanced patch
that was prepared to record the pre- and post-image object
name in full, and the path being patched exactly matches
the object the patch applies to (i.e. "index" line's
pre-image object name is what is in the working tree),
and the post-image object is available in the object
database, use the post-image object as the patch
result. This allows binary files to be patched in a
very limited way.

SYNOPSIS
--------
'git-<command>' <args>
'git' [--version] [--exec-path[=GIT_EXEC_PATH]] [--help] COMMAND [ARGS]
DESCRIPTION
-----------
'git' is both a program and a directory content tracker system.
The program 'git' is just a wrapper to reach the core git programs
(or a potty if you like, as it's not exactly porcelain but still
brings your stuff to the plumbing).
This is reference information for the core git commands.
OPTIONS
-------
--version::
prints the git suite version that the 'git' program came from.
--help::
prints the synopsis and a list of available commands.
If a git command is named this option will bring up the
man-page for that command.
--exec-path::
path to wherever your core git programs are installed.
This can also be controlled by setting the GIT_EXEC_PATH
environment variable. If no path is given 'git' will print
the current setting and then exit.
