+--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

+NOT LEARNING CORE GIT COMMANDS
+------------------------------
+
+This manual is intended to give complete background information
+and internal workings of git, which may be too much for most
+people. The <<Discussion>> section below contains much useful
+definition and clarification - read that first.
+
+If you are interested in using git to manage (version control)
+projects, use link:everyday.html[Everyday GIT] as a guide to the
+minimum set of commands you need to know for day-to-day work.
+Most likely, that will get you started, and you can go a long
+way without knowing the low level details too much.
+
+The link:tutorial.html[tutorial] document covers how things
+internally work.
+
+If you are migrating from CVS, link:cvs-migration.html[cvs
+migration] document may be helpful after you finish the
+tutorial.
+
+After you get the general feel from the tutorial and this
+overview page, you may want to take a look at the
+link:howto-index.html[howto] documents.

+
+CORE GIT COMMANDS
+-----------------
+
+If you are writing your own Porcelain, you need to be familiar
+with most of the low level commands --- I suggest starting from
+gitlink:git-update-index[1] and gitlink:git-read-tree[1].
