Big tool rename.

As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.

+git-update-index(1)
+===================
+v0.1, May 2005
+
+NAME
+----
+git-update-index - Modifies the index or directory cache
+
+
+SYNOPSIS
+--------
+'git-update-index'
+	     [--add] [--remove] [--refresh] [--replace]
+	     [--ignore-missing]
+	     [--force-remove]
+	     [--cacheinfo <mode> <object> <file>]\*
+	     [--info-only]
+	     [--] [<file>]\*
+
+DESCRIPTION
+-----------
+Modifies the index or directory cache. Each file mentioned is updated
+into the cache and any 'unmerged' or 'needs updating' state is
+cleared.
+
+The way "git-update-index" handles files it is told about can be modified
+using the various options:
+
+OPTIONS
+-------
+--add::
+	If a specified file isn't in the cache already then it's
+	added.
+	Default behaviour is to ignore new files.
+
+--remove::
+	If a specified file is in the cache but is missing then it's
+	removed.
+	Default behaviour is to ignore removed file.
+
+--refresh::
+	Looks at the current cache and checks to see if merges or
+	updates are needed by checking stat() information.
+
+--ignore-missing::
+	Ignores missing files during a --refresh
+
+--cacheinfo <mode> <object> <path>::
+	Directly insert the specified info into the cache.
+	
+--info-only::
+	Do not create objects in the object database for all
+	<file> arguments that follow this flag; just insert
+	their object IDs into the cache.
+
+--force-remove::
+	Remove the file from the index even when the working directory
+	still has such a file. (Implies --remove.)
+
+--replace::
+	By default, when a file `path` exists in the index,
+	git-update-index refuses an attempt to add `path/file`.
+	Similarly if a file `path/file` exists, a file `path`
+	cannot be added.  With --replace flag, existing entries
+	that conflicts with the entry being added are
+	automatically removed with warning messages.
+
+--::
+	Do not interpret any more arguments as options.
+
+<file>::
+	Files to act on.
+	Note that files begining with '.' are discarded. This includes
+	`./file` and `dir/./file`. If you don't want this, then use	
+	cleaner names.
+	The same applies to directories ending '/' and paths with '//'
+
+Using --refresh
+---------------
+'--refresh' does not calculate a new sha1 file or bring the cache
+up-to-date for mode/content changes. But what it *does* do is to
+"re-match" the stat information of a file with the cache, so that you
+can refresh the cache for a file that hasn't been changed but where
+the stat entry is out of date.
+
+For example, you'd want to do this after doing a "git-read-tree", to link
+up the stat cache details with the proper files.
+
+Using --cacheinfo or --info-only
+--------------------------------
+'--cacheinfo' is used to register a file that is not in the
+current working directory.  This is useful for minimum-checkout
+merging.
+
+  To pretend you have a file with mode and sha1 at path, say:
+
+   $ git-update-index --cacheinfo mode sha1 path
+
+'--info-only' is used to register files without placing them in the object
+database.  This is useful for status-only repositories.
+
+Both '--cacheinfo' and '--info-only' behave similarly: the index is updated
+but the object database isn't.  '--cacheinfo' is useful when the object is
+in the database but the file isn't available locally.  '--info-only' is
+useful when the file is available, but you do not wish to update the
+object database.
+
+Examples
+--------
+To update and refresh only the files already checked out:
+
+   git-checkout-index -n -f -a && git-update-index --ignore-missing --refresh
