FOP stands for '''F'''ormatting '''O'''bjects '''P'''rocessor. This is the name of [Apache]'s [http://xml.apache.org/] [xsl-fo] processor for [XML]. It basically allows conversion of [XML] documents into binary formats, for instance [PDF]. Currently only a [Java] version is available, which could be used with [TclBlend] or [Jacl], or directly [exec]'d from Tcl. I ([NEM]) sometime dream about writing an [xsl-fo] processor for [tdom], but it would be a huge project (read the xsl-fo specs from the w3c for an idea of the complexity involved). ---- [Category Acronym]
