List of parameters in *.ftl files

Hi,

Where or How can I get the list of parameters which using in *.ftl files.

Like these:

@common.short_build_info
${build.triggeredBy.user.descriptiveName}

I need that when I deploy by -  buildType.name = "Java deploy to QA1"
I can sent mail like this:

<#global body>

Environment:                QA1
Release Version:         R10
SVN Branch:              " last successful - link like this R10-15556  " - which is in href='http://localhost:8111/viewLog.html?buildTypeId=bt11&buildId=lastSuccessful'
</#global>

How can I join ${project.name} :: ${buildType.name} ::short_build_info (for example)?

Thanks.
