 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.
