## Place text on the current figure using the mouse.
##
## The string argument @var{s} may be a character array or a cell array
## of strings.  If @var{s} has more than one row, each row is used
## to create a separate text object after a mouse click.  For example:
##
## Place a single string after one mouse click
##
## @example
## gtext ("I clicked here")
## @end example
##
## Place two strings after two mouse clicks
##
## @example
## gtext (@{"I clicked here"; "and there"@})
## @end example
##
## Place two strings, each with two lines, after two mouse clicks
##
## @example
## gtext (@{"I clicked", "here"; "and", "there"@})
## @end example
##
## Optional @var{property}/@var{value} pairs are passed directly to the
## underlying text objects.
##
## The optional return value @var{h} holds the graphics handle(s) to the
## created text object(s).
