-Cscope Notes:
-
-The nvi tags structure has been reworked to handle the notion of multiple
-locations per tag.  This supports cscope, which returns multiple locations
-per query.  It will hopefully support ctags programs that create databases
-with multiple locations per tag as well.
-
-There is now a list of "tag queues" chained from each screen.  Each tag
-queue has one or more "tag locations".
-
-   +----+    +----+	+----+     +----+
-   | EP | -> | Q1 | <-- | T1 | <-- | T2 |
-   +----+    +----+ --> +----+ --> +----+
-  	     |
-  	     +----+     +----+
-  	     | Q2 | <-- | T1 |
-  	     +----+ --> +----+
-  	     |
-  	     +----+	+----+
-  	     | Q3 | <-- | T1 |
-  	     +----+ --> +----+
-  
-In the above diagram, each "Q" is a "tag queue", and each "T" is a
-tag location.  Generally, the commands:
-
-	:tag			create a new Q
-	^[			create a new Q
-	:cscope find		create a new Q
-	:tagnext		move to the next T
-	:tagprev		move to the previous T
-	:tagpop			discard one or more Q's
-	^T			discard the most recent Q
-	:tagtop			discard all Q's
-
-More specifically:
-
-:cs[cope] a[dd] cscope-dir
-
-	Attach to the cscope database in cscope-dir.
-
-:cs[cope] f[ind] c|d|e|f|g|i|s|t buffer|pattern
-
-	Query all attached cscopes for the pattern.  The pattern is a
-	regular expression.  If the pattern is a double-quote character
-	followed by a valid buffer name (e.g., "t), then the contents
-	of the named buffer are used as the pattern.
-
-	c: find callers of name
-	d: find all function calls made from name
-	e: find pattern
-	f: find files with name as substring
-	g: find definition of name
-	i: find files #including name
-	s: find all uses of name
-	t: find assignments to name
-
-	The find command pushes the current location onto the tags stack,
-	and switches to the first location resulting from the query, if
-	the query returned at least one result.
-
-:cs[cope] h[elp] [command]
-	
-	List the cscope commands, or usage help on one command.
-
-:display c[onnections]
-
-	Display the list of cscope connections
-
-:display t[ags]
-
-	The tags display has been enhanced to display multiple tag
-	locations per tag query.
-
-:cs[cope] k[ill] #
-
-	Kill cscope connection number #.
-
-:cs[cope] r[eset]
-	Kill all attached cscopes.  Useful if one got hung but you don't
-	know which one.
-
-:tagn[ext][!]
-
-	Move to the next tag resulting from a query.
-
-:tagpr[ev][!]
-
-	Return to the previous tag resulting from a query.
-
-:tagp[op], ^T
-
-	Return to the previous tag group (no change).
-
-:tagt[op]
-
-	Discard all tag groups (no change).
-
-Suggested maps:
-
-	" ^N: move to the next tag
-	map ^N :tagnext^M
-	" ^P: move to the previous tag
-	map ^P :tagprev^M
-
-	" Tab+letter performs a C-Scope query on the current word.
-	" C-Scope 12.9 has a text-string query (type t).
-	" C-Scope 13.3 replaces it with an assignment query; hence a==t.
-	map <tab>a "tye:csc find t"t
-	map <tab>c "tye:csc find c"t
-	map <tab>d "tye:csc find d"t
-	map <tab>e "tye:csc find e"t
-	map <tab>f "tye:csc find f"t
-	map <tab>g "tye:csc find g"t
-	map <tab>i "tye:csc find i"t
-	map <tab>s "tye:csc find s"t
-	map <tab>t "tye:csc find t"t
-
-To start nvi with an initial set of cscope directories, use the environment
-variable CSCOPE_DIRS.  This variable should contain a <blank>-separated
-list of directories containing cscope databases.  (This MAY be changed to
-be an edit option, I haven't really decided, yet.)
-
-Each cscope directory must contain a file named "cscope.out" which is the
-main cscope database, or nvi will not attempt to connect to a cscope to
-handle requests for that database.
-
-The file "cscope.tpath" may contain a colon-separated directory search
-path which will be used to find the files reported by cscope.  If this
-cscope.tpath does not exist, then the paths are assumed to be relative to
-the cscope directory itself.  This is an extension to the standard cscope,
-but seems important enough to keep.
