# blahtexml(1)

Converts TeX equations into MathML

## NAME

blahtexml - Converts TeX equations into MathML

## SYNOPSIS

**blahtexml** \[*options*\] *files*...

## DESCRIPTION

This manual page documents briefly the **blahtexml** command.

**blahtexml** converts an equation given in a syntax close to TeX into MathML. Blahtexml is a simple extension of blahtex. In addition to the functionality of blahtex, blahtexml has XML processing in mind and is able to process a whole XML document into another XML document. Instead of converting only one formula at a time, blahtexml can convert all the formulas of the given XML file into MathML.

## OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (\`-'). A summary of options is included below. For a complete description, see the online documentation.

- **--help**

  Show summary of options.

- **--texvc-compatible-commands**

  Enables use of commands that are specific to texvc, but that are not standard TeX/LaTeX/AMS-LaTeX commands.

- **--print-error-messages**

  This will print out a list of all error IDs and corresponding messages that blahtex can possibly emit inside an \<error\> block.

## MATHML OPTIONS

These options control the MathML output of the blahtexml program.

- **--mathml**

  Enables MathML output.

- **--xmlin**

  This allows one to embed TeX equations in an existing MathML code, using a special notation. The equations are given as attributes (inline or block) in the http://gva.noekeon.org/blahtexml namespace. Whenever blahtexml meets such an equation, it expands it into the equivalent MathML code.

  For more information check

  http://gva.noekeon.org/blahtexml/how\_to\_use.html

  or the blahtexml manual.

- **--annotate-TeX**

  Produces TeX annotations in the MathML output.

- **--annotate-PNG**

  Produces PNG files and annotates the MathML output with the PNG file name.
