Template class.

Nathan Codding - Original version design and implementation
|
|
Crimsonbane - Initial caching proposal and work
|
|
psoTFX - Completion of file caching, decompilation routines and implementation of
|
|
conditionals/keywords and associated changes
|
|
|
|
The interface was inspired by PHPLib templates, and the template file (formats are
|
|
quite similar)
|
|
|
|
The keyword/conditional implementation is currently based on sections of code from
|
|
the Smarty templating engine (c) 2001 ispi of Lincoln, Inc. which is released
|
|
(on its own and in whole) under the LGPL. Section 3 of the LGPL states that any code
|
|
derived from an LGPL application may be relicenced under the GPL, this applies
|
|
to this source
