  It is implemented in the Python scripting language. It uses only core
Python modules (expat XML parser, unicode database, something other),
so it should work on any recent system. Mapping from Unicode characters
to LaTeX commands is taken from attachment for the MathML specification
(http://www.w3.org/Math/characters/unicode.xml (note: 1,5 Mb)).

  It is hard to said exactly, but I think it is fast. In any case,
it should be faster then processing of specials by xslt.

  The processor does not know about \usepackage, it only translates
characters. It is a task of an xslt to insert \usepackage command into
the output, if required.

  User can specify an output encoding. The processor attempts to make as
good translation as possible for it. For example, for letter &szlig;, if
output encoding is ascii, then processor outputs "\ss "; if output
encoding is latin1, then processor outputs "ъ". In latter case correct
header should be \usepackage[latin1]{inputenc}, but it is not a task of
processor to create this header.
