perl Makefile.PL TT_XS_DEFAULT=y TT_ACCEPT=y
TT_XS_ENABLE Enable XS Stash (y)
TT_XS_DEFAULT Use XS Stash by default (y)
TT_QUIET no messages (n)
TT_ACCEPT accept defaults (n)

prompting for confirmation of the various configuration
options. Setting the TT_ACCEPT option causes the default
value (possibly modified by other command line options)
to be accepted. The TT_QUIET option can also be set to
suppress the prompt messages.

IMPORTANT NOTE:
You have version $Template::VERSION of the Template Toolkit installed.
There are some minor incompatabilities between version 1 and 2
of the Template Toolkit which you should be aware of. Installing
this version will overwrite your version $Template::VERSION files
unless you take measures to install one or the other version in a
different location (i.e. perl Makefile.PL PREFIX=/other/path).
Please consult the README and Changes file for further details.
Most of the changes are in the more obscure features and
directives so hopefully you will find the upgrade process fairly
painless. If you're feeling brave, then answer 'y', otherwise 'n'.

Template::Stash::XS
-------------------
The Template::Stash module is a core part of the Template Toolkit,
implementing the magic for accessing data using the dot notation.
There is a high speed version, Template::Stash::XS, written in C.
This makes the Template Toolkit run about twice as fast as when using
the regular Template::Stash written in Perl. If you've got a C
compiler on your system then you can elect to have the XS Stash built.
You can also specify that you want to use the XS Stash by default.
Note that as of version 2.15 the XS Stash now supports access to tied
hashes and arrays.
See 'perldoc Template::Config' for further details.

Optional Extras
---------------
In additional to the Perl modules and POD documentation installed in
the usual way, the Template Toolkit distribution also contains a
number of optional components:
* Template libaries for basic HTML, Pod -> HTML, and PostScript
* Splash! - a stylish HTML user interface template library / widget set
* HTML documentation - distributed in template form for customisation
* Stylesheet templates to generate docs as vanilla HTML or using Splash!
* Examples - numerous examples of using the template libraries
If you want to install these optional components then you'll need to
specify a separate directory for them.

Splash!
-------
The Splash! template library uses a number of (very) small images to
build user interface components. These will be installed into the
directory:
$TT_PREFIX/images
EOF
if ($WIN32) {
# default images value for Win32 to browse via file system
$TT_IMAGES = "$TT_PREFIX/images";
message(<<EOF);
If you want to use the Splash! library then you'll need to make sure
you can access these images via your browser. If you want to deliver
pages via a web server then you'll need to specify the URL that can be
use to access these images. In the general case you can accept the
default and access the images via the filesystem.
EOF
}
else {
message(<<EOF);
If you want to use the Splash! library then you'll need to copy these
images, define an alias (e.g. in the httpd.conf) or create a symbolic
link to them so that your web server can find them. Then you'll need
to specify the resulting URL which can be used to retrieve them from
the web server.
Typical values might be '/tt2/images', '/images/tt2', '/~user/tt2/images'
or even something like 'http://www.yourhost.org/images/tt2'.
(NOTE: If this is too much for you to think about right now, then
accept the default below and read the Template::Library::Splash
manpage at your leisure to find out more).

HTML Documentation
------------------
The modules comprising the Template Toolkit contain comprehensive POD
documentation which can be browsed using 'perldoc' or 'man' (if your
system supports it). In additional, the distribution also includes a
set of source templates and style elements for generating the same
documentation in HTML format. These will be installed in the
directory:
$TT_PREFIX/docs
The HTML documentation can be built for you at "make install" time in
a plain and simple HTML format or using the Splash! library. You can
see examples of these different styles and browse the documentation
online at:
http://www.template-toolkit.org/docs/
