+The approach is to emulate TeX as far as possible (in Perl),
+converting the TEX or (LATEX) document into LATExml’s XML format. That
+format is modelled on the typical document structure found in LATEX,
+and inspired by HTML, MathML, OpenMath and others. That abstract
+document is then further transformed into HTML of various flavors,
+with MathML and SVG, or into JATS or ePub or …. Of course, emulating
+TEX is kinda hard, there are many clever LATEX package developers, and
+the Web moves quickly, so there are gaps in fidelity and coverage.
+
+But for simple cases it might work just like this:
+
+latexml --dest=mydoc.xml mydoc
+latexmlpost --dest=somewhere/mydoc.html mydoc.xml

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
