SYNOPSIS
--------
-'git-<command>' <args>
+'git' [--version] [--exec-path[=GIT_EXEC_PATH]] [--help] COMMAND [ARGS]
DESCRIPTION
-----------
-
-This is reference information for the core git commands.
-
+'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).
+
+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.

+Configuration Mechanism
+-----------------------
+
+Starting from 0.99.9 (actually mid 0.99.8.GIT), .git/config file
+is used to hold per-repository configuration options. It is a
+simple text file modelled after `.ini` format familiar to some
+people. Here is an example:
+
+------------
+#
+# This is the config file, and
+# a '#' or ';' character indicates
+# a comment
+#
+
+; core variables
+[core]
+ ; Don't trust file modes
+ filemode = false
+
+; user identity
+[user]
+ name = "Junio C Hamano"
+ email = "junkio@twinsun.com"
+
+------------
+
+Various commands read from the configuration file and adjust
+their operation accordingly.
