NAME
    Template::Plugin::Cache - cache output of templates

SYNOPSIS
      [% USE cache = Cache%]
    
      [% cache.inc(
                   'template' => 'slow.html',
                   'keys' => {'user.name' => user.name},
                   'ttl' => 360
                   ) %]

DESCRIPTION
    The Cache plugin allows you to cache generated output from a template.
    You load the plugin with the standard syntax:

        [% USE cache = Cache %]

    This creates a plugin object with the name 'cache'. You may also specify
    parameters for the File::Cache module, which is used for storage.

        [% USE mycache = Cache(namespace => 'MyCache') %]

    The only methods currently available are include and process,
    abbreviated to "inc" and "proc" to avoid clashing with built-in
    directives. They work the same as the standard INCLUDE and PROCESS
    directives except that they will first look for cached output from the
    template being requested and if they find it they will use that instead
    of actually running the template.

      [% cache.inc(
                   'template' => 'slow.html',
                   'keys' => {'user.name' => user.name},
                   'ttl' => 360
                   ) %]

    The template parameter names the file or block to include. The keys are
    variables used to identify the correct cache file. Different values for
    the specified keys will result in different cache files. The ttl
    parameter specifies the "time to live" for this cache file, in seconds.

    Why the ugliness on the keys? Well, the TT dot notation can only be
    resolved correctly by the TT parser at compile time. It's easy to look
    up simple variable names in the stash, but compound names like
    "user.name" are hard to resolve at runtime. I may attempt to fake this
    in a future version, but it would be hacky and might cause problems.
