ATTRIBUTES

       "name"
           The "name" attribute selects which logo is wanted. The table above lists valid names,
           and wml is used by default.

       "base"
           Usually the logos are copied into logo-xxxxxx.png where "xxxxxx" is the name of the
           logo.  When you use a "base=foo" attribute, then the resulting files are named
           foo.logo-xxxxxx.png.  Actually you can even use a complete filename including a
           directory prefix, i.e. when you use "base=../../common/foo" attribute, then the images
           are created as ../../common/foo.logo-xxxxxx.png.

           And for most flexibility when no base is specified and the variable "LOGO_BASE" is
           defined (usually from within a .wmlrc file via "-LOGO_BASE~path/to/logo/dir/base") it
           is used.  Use this feature to copy the logos to a particular directory.

           You may also use the variable "IMAGE_BASE" which defines in a single line all base
           names for images generated by WML.

       "format"
           Logos are available in PNG or GIF formats. This attribute is the filename extension of
           the desired format, i.e. respectively "png" and "gif".  Default is "png" extension ;
           this default can be changed via the "IMAGE_FORMAT" variable.

       "file"
           This attribute defines the logo filename. It overrides all other computed values.

       "target"
           If the "target" attribute is used, it refers to a target frame or window where the
           hyperlink is redirected to.

       "notag"
           This forces "<logo>" to expand to nothing, i.e. no resulting "<img>" tag. The image
           itself is still generated. In combination with the above "file" attribute this can be
           used to generate images to particular files which can be used at other positions, for
           instance inside "<rollover>" (see wml::des::rollover(3)) tags.

EXAMPLE

       This example only copy the vim logo to "$(IMAGES)/logo-vim.png" without any output:

        <logo name=vim format=png base="$(IMAGES)/logo" notag>

HISTORY

        For backward compatibility a logo named "php3" is also available.
        Inluding the version number was not a really good idea, use the
        logo "php" instead. Expect that the logo "php3" will be removed in
        future releases.
