    <TMPL_IF var><TMPL_VAR foo></tmpl_if var>
    <!-- TMPL_IF var --><!-- TMPL_VAR foo --><!-- /tmpl_if var -->
    <%if var %><%= foo %><%/if var %>

Optional tagstyle 'tt':

    [%if var %][%= foo %][%/if var %]


    <%= %>
    outputs foo in the cuurent position of the stash and is the same as
    <%= foo %>
    <%= .config.url %>
    goes to root of parameter stash; like $params->{config}->{url}
    <%= %>
    goes one level up in stash
    <%= list[3].keyname.method %>
    acts like: $stash->[3]->{keyname}->method


    <%var foo%> or <%= foo%>
conditions like in Perl
for-loop and while-loop like in Perl.

    <%loop cds%><%= __counter__%>. Title: <%= _.title%><%/loop cds%>
    <%loop cds join=", " %><%= _.title%><%/loop cds%>
    <%while><%= __counter__%>. <%= %><%/while %>
    <%each hashref%><%= __key__ %>=<%= __value__ %><%/each %> (sorted alphanumeric)
    <%each hashref sort=alpha %><%= __key__ %>=<%= __value__ %><%/each %> (sorted alphanumeric)
    <%each hashref sort=num %><%= __key__ %>=<%= __value__ %><%/each %> (sorted numeric)
    <%each hashref sort=0 %><%= __key__ %>=<%= __value__ %><%/each %> (not sorted)
    <%with cds[0].artist.fanclub%><%= _.address%><%= _.homepage%><%/with %>
    <%include_var param_with_template_name%>
    <%comment explanation %>
    This will not appear in the rendered template.
    blah blah...
    <%/comment explanation %>
    <%switch .config.language%>
    <%case de%>Hallo
    <%case es%>Hola
    <%case en,default%>Hello
    <%/switch .config.language%>
See section Perl in HTML::Template::Compiled


Each attribute can be written as

    attribute="some thing"
    attribute='some "thing"'
You can omit the 'name=' here.

    <%if var%>var<%elsif name=var2%>var4<%/if%>

Can be used in all tags.

    <%= message escape=html %>
    <%= params escape=url %>
    <%= params escape=js %>
    <%= some_var escape=dump|html%>

Can be used in "VAR"-tags.

    <%= this.var.might_be_undef default="my fault" %>

Can be used in "VAR"-tags.

    <%loop cds alias="cd" %><%= $cd.title %><%/loop cds %>

Can be used in "LOOP" and "WHILE". Works like "SET_VAR" and is short for

    <%loop cds %><%set_var cd value=_ %><%= cd.title %><%/loop cds %>

Useful for nested loops.

    <%set_var myvar value=.another.var %>
    <%set_var myvar2 expr="60 * 60 * 24" %>

This creates a variable similar to a package var with local() in perl.

    <!-- recognize myvar and myvar2 as variables not parameter stash -->
    <%use_vars myvar,myvar2 %>
    myvar: <%= myvar %>
    <%loop cds join=", " %><%= _.title%><%/loop cds%>

can be used in "LOOP"

    <%loop cds break="3" %>
    <%= _.title%><%if __break__ %>\n</%if %>
    <%/loop cds%>

Sets "__break__" to 1 every xth loop. Can be used in "LOOP", "WHILE" and "EACH"


    <%= __index__         %> the current loop index starting at 0
    <%= __counter__       %> the current loop index starting at 1
    <%= __first__         %> true if first iteration
    <%= __last__          %> true if last iteration
    <%= __odd__           %> true if __counter__ is odd
    <%= __inner__         %> true if not last or first iteration
    <%= __key__           %> the key of an EACH iteration
    <%= __value__         %> the value of an EACH iteration
    <%= __break__         %> see L<"BREAK"> above
    <%= __filename__      %> filename of current template (since 0.91_001)
    <%= __filenameshort__ %> short filename of current template (since 0.91_001)
