+sign_define({name} [, {dict}])				*sign_define()*
+		Define a new sign named {name} or modify the attributes of an
+		existing sign.  This is similar to the |:sign-define| command.
+
+		Prefix {name} with a unique text to avoid name collisions.
+		There is no {group} like with placing signs.
+
+		The {name} can be a String or a Number.  The optional {dict}
+		argument specifies the sign attributes.  The following values
+		are supported:
+		    icon	full path to the bitmap file for the sign.
+		    linehl	highlight group used for the whole line the
+				sign is placed in.
+		    text	text that is displayed when there is no icon
+				or the GUI is not being used.
+		    texthl	highlight group used for the text item
+		For an existing sign, the attributes are updated.
+
+		Returns 0 on success and -1 on failure.
+
+		Examples: >
+			call sign_define("mySign", {"text" : "=>", "texthl" :
+					\ "Error", "linehl" : "Search"})

+sign_getdefined([{name}])				*sign_getdefined()*
+		Get a list of defined signs and their attributes.
+		This is similar to the |:sign-list| command.
+
+		If the {name} is not supplied, then a list of all the defined
+		signs is returned. Otherwise the attribute of the specified
+		sign is returned.
+
+		Each list item in the returned value is a dictionary with the
+		following entries:
+			icon	full path to the bitmap file of the sign
+			linehl	highlight group used for the whole line the
+				sign is placed in.
+			name	name of the sign
+			text	text that is displayed when there is no icon
+				or the GUI is not being used.
+			texthl	highlight group used for the text item
+
+		Returns an empty List if there are no signs and when {name} is
+		not found.

+sign_getplaced([{expr} [, {dict}]])			*sign_getplaced()*
+		Return a list of signs placed in a buffer or all the buffers.
+		This is similar to the |:sign-place-list| command.
+
+		If the optional buffer name {expr} is specified, then only the
+		list of signs placed in that buffer is returned.  For the use
+		of {expr}, see |bufname()|. The optional {dict} can contain
+		the following entries:
+			group	select only signs in this group
+			id	select sign with this identifier
+			lnum	select signs placed in this line. For the use
+				of {lnum}, see |line()|.
+		If {group} is '*', then signs in all the groups including the
+		global group are returned. If {group} is not supplied, then
+		only signs in the global group are returned.  If no arguments
+		are supplied, then signs in the global group placed in all the
+		buffers are returned.
+
+		Each list item in the returned value is a dictionary with the
+		following entries:
+			bufnr	number of the buffer with the sign
+			signs	list of signs placed in {bufnr}. Each list
+				item is a dictionary with the below listed
+				entries
+
+		The dictionary for each sign contains the following entries:
+			group	sign group. Set to '' for the global group.
+			id	identifier of the sign
+			lnum	line number where the sign is placed
+			name	name of the defined sign
+			priority	sign priority
+
+		Returns an empty list on failure.
+
+		Examples: >
+			" Get a List of signs placed in eval.c in the

+sign_place({id}, {group}, {name}, {expr} [, {dict}])
+		Place the sign defined as {name} at line {lnum} in file {expr}
+		and assign {id} and {group} to sign.  This is similar to the
+		|:sign-place| command.
+
+		If the sign identifier {id} is zero, then a new identifier is
+		allocated.  Otherwise the specified number is used. {group} is
+		the sign group name. To use the global sign group, use an
+		empty string.  {group} functions as a namespace for {id}, thus
+		two groups can use the same IDs.
+		
+		{name} refers to a defined sign.
+		{expr} refers to a buffer name or number. For the accepted
+		values, see |bufname()|.
+
+		The optional {dict} argument supports the following entries:
+			lnum		line number in the buffer {expr} where
+					the sign is to be placed. For the
+					accepted values, see |line()|.
+			priority	priority of the sign. See
+					|sign-priority| for more information.
+
+		If the optional {dict} is not specified, then it modifies the
+		placed sign {id} in group {group} to use the defined sign
+		{name}.
+
+		Returns the sign identifier on success and -1 on failure.
+
+		Examples: >
+			" Place a sign named sign1 with id 5 at line 20 in
+			" buffer json.c
+			call sign_place(5, '', 'sign1', 'json.c',
+							\ {'lnum' : 20})
+
+			" Updates sign 5 in buffer json.c to use sign2
+			call sign_place(5, '', 'sign2', 'json.c')
+
+			" Place a sign named sign3 at line 30 in
+			" buffer json.c with a new identifier
+			let id = sign_place(0, '', 'sign3', 'json.c',
+							\ {'lnum' : 30})
+
+			" Place a sign named sign4 with id 10 in group 'g3'
+			" at line 40 in buffer json.c with priority 90
+			call sign_place(10, 'g3', 'sign4', 'json.c',

+sign_undefine([{name}])					*sign_undefine()*
+		Deletes a previously defined sign {name}. This is similar to
+		the |:sign-undefine| command. If {name} is not supplied, then
+		deletes all the defined signs.
+
+		Returns 0 on success and -1 on failure.
+
+		Examples: >
+			" Delete a sign named mySign
+			call sign_undefine("mySign")
+
+			" Delete all the signs
+			call sign_undefine()
+<
+sign_unplace({group} [, {dict}])			*sign_unplace()*
+		Remove a previously placed sign in one or more buffers.  This
+		is similar to the |:sign-unplace()| command.
+
+		{group} is the sign group name. To use the global sign group,
+		use an empty string.  If {group} is set to '*', then all the
+		groups including the global group are used.
+		The signs in {group} are selected based on the entries in
+		{dict}.  The following optional entries in {dict} are
+		supported:
+			buffer	buffer name or number. See |bufname()|.
+			id	sign identifier
+		If {dict} is not supplied, then all the signs in {group} are
+		removed.
+
+		Returns 0 on success and -1 on failure.
+
+		Examples: >
+			" Remove sign 10 from buffer a.vim
+			call sign_unplace('', {'buffer' : "a.vim", 'id' : 10})
+
+			" Remove sign 20 in group 'g1' from buffer 3
+			call sign_unplace('g1', {'buffer' : 3, 'id' : 20})
+
+			" Remove all the signs in group 'g2' from buffer 10
+			call sign_unplace('g2', {'buffer' : 10})
+
+			" Remove sign 30 in group 'g3' from all the buffers
+			call sign_unplace('g3', {'id' : 30})
+
+			" Remove all the signs placed in buffer 5
+			call sign_unplace('*', {'buffer' : 5})
+
+			" Remove the signs in group 'g4' from all the buffers
+			call sign_unplace('g4')
+
+			" Remove sign 40 from all the buffers
+			call sign_unplace('*', {'id' : 40})
+
+			" Remove all the placed signs from all the buffers
+			call sign_unplace('*')
