LaTeX needs "standalone" package to achieve similar behavior. Another difference with ConTeXt is that you can include multiple \environment commands. So instead of having all of your customization in one environment file, you could (for example) have environment files for different things, like -> a particular choice of typefaces -> your own macro definitions -> customizations for the way chapter and section heading are laid out -> customizations for how the table of contents is done. So at the beginning of a document you could pick and choose among your various environment files to set up the look of a document the way you want, without having to have one "preamble" for every possible combination. So (as I understand it) this is a fair bit different than how LaTeX does things. >> Also, the chapters in the document I am editing start like this: >> \environment ../introCTX_env.tex >> \startcomponent b08_Lists.tex >> \startchapter >> [ >> reference=cap:toc, >> title={Table of contents, indexes, lists}, >> bookmark={Table of contents, indexes, lists}, >> ] >> so "\startcomponent" can be used instead of "\starttext" to say "the >> preamble is over, here comes the content". >> And there is also \startTEXpage to start the document body.

I took a very quick look at the code right now, and while someone more familiar with the code base might see how to do that immediately, for me it will be another research project. ;-) Jim
