swfmill is an xml2swf and swf2xml processor with import
functionalities.
Its most common use is the generation of asset libraries containing
images (PNG and JPEG), fonts (TTF) or other SWF movies for use with
MTASC- or haXe-compiled ActionScript, although swfmill can be used to
produce both simple and complex SWF structures.
* built around an XSLT/EXSLT processor (libxslt)
* input and output of the XSLT transformation can be either XML or
binary SWF
* XSLT commands for importing PNG, JPEG, TTF and SWF, and for mapping
SWF ID numbers
* built-in "simple dialect" to support library creation and building
simple SWFs
