-SNiFF+ and Vim				    *sniff*
-
-1. Introduction				    |sniff-intro|
-2. Commands				    |sniff-commands|
-3. Compiling Vim with SNiFF+ interface	    |sniff-compiling|
-
-{Vi does not have any of these commands}  *E275* *E274* *E276* *E278* *E279*
-
-The SNiFF+ interface only works, when Vim was compiled with the |+sniff|
-feature.
-
-==============================================================================
-1. Introduction					*sniff-intro*
-
-The following features for the use with SNiFF+ are available:
-
-   * Vim can be used for all editing requests
-   * SNiFF+ recognizes and updates all browsers when a file is saved in Vim
-   * SNiFF+ commands can be issued directly from Vim
-
-How to use Vim with SNiFF+
-   1. Make sure SNiFF+ is running.
-   2. In the Editor view of the Preferences dialog set the Field named
-      'External Editor' to 'Emacs/Vim'.
-   4. Start Vim
-   5. Connect to SNiFF+ (:sniff connect)
-
-Once a connection is established, SNiFF+ uses Vim for all requests to show or
-edit source code.  On the other hand, you can send queries to SNiFF+ with the
-:sniff command.
-
-==============================================================================
-2. Commands				    *sniff-commands*
-
-			    *:sniff* *:sni*
-:sni[ff] request [symbol]   Send request to sniff with optional symbol.
-			    {not in Vi}
-:sni[ff]		    Display all possible requests and the connection
-			    status
-
-Most requests require a symbol (identifier) as parameter.  If it is omitted,
-Vim will use the current word under the cursor.
-The available requests are listed below:
-
-request		      mapping	description
--------------------------------------------------------------------------------
-connect			sc	Establish connection with SNiFF+.
-				Make sure SNiFF+ is prepared for this in the
-				Preferences
-disconnect		sq	Disconnect from SNiFF+.  You can reconnect any
-				time with :sniff connect (or 'sc')
-toggle			st	Toggle between implementation
-				and definition file
-find-symbol		sf	Load the symbol into a Symbol Browser
-browse-class		sb	Loads the class into a Class Browser
-superclass		ss	Edit superclass of symbol
-overridden		so	Edit overridden method of symbol
-retrieve-file		srf	Retrieve symbol in current file
-retrieve-project	srp	Retrieve symbol in current project
-retrieve-all-projects	srP	Retrieve symbol in all projects
-retrieve-next		sR	Retrieve symbol using current Retriever
-				settings
-goto-symbol		sg	Goto definition or implementation of symbol
-hierarchy		sh	Load symbol into the Hierarchy Browser
-restr-hier		sH	same as above but show only related classes
-xref-to			sxt	Start a refers-to query on symbol and
-				load the results into the Cross Referencer
-xref-by			sxb	Start a referred-by query on symbol
-xref-has		sxh	Start a refers-to components query on symbol
-xref-used-by		sxu	Start a referred-by as component query on
-				symbol
-show-docu		sd	Show documentation of symbol
-gen-docu		sD	Generate documentation of symbol
-
-The mappings are defined in a file 'sniff.vim', which is part of every SNiFF+
-product ($SNIFF_DIR/config/sniff.vim).  This file is sourced whenever Vim
-connects to SNiFF+.
-
-==============================================================================
-3. Compiling Vim with SNiFF+ interface		*sniff-compiling*
-
-To compile Vim with SNiFF+ support, you need two source files of the extra
-archive: if_sniff.c and if_sniff.h.
-On Unix: Edit the Makefile and uncomment the line "--enable-sniff".  Or run
-configure manually with this argument.
-On NT: Specify SNIFF=yes with your make command.
+The SNiFF+ support was removed at patch 7.4.1433.  If you want to check it out
+sync to before that.
