sgmltools-lite is a package whose purpose is to simplify the document creation process from SGML to some other format. It takes the complexity of the various commands involved and takes care of
all the invocations and the options required. I used sgmltools-lite-3.0.2-164. However, the current version of the scripts does not use sgmltools anymore, so you don't need it. Some code of the
print.dsl file of this package was used in the lyxtox stylesheets, but again, no changes are needed on your part.
