List Special Variables
FreeMarker is a java based template engine for complex template processing.
This requires the library freemarker-2.3.16.jar to be in classpath.
The following example shows using LOOPVAR _index and LOOPVAR _has_next special loop variables.
The first one is a loop count index and other is a boolean specifying whether the current
item is last in the sequence or not.
1<#list ["ONE", "TWO", "THREE", "FOUR"] as n>
2${n_index + 1}. ${n} <#if n_has_next>(has next)</#if>
5<#list 10000..10004 as a>
6${a_index + 1}. ${a} <#if a_has_next>(has next)</#if>
