NAME
    MathML::itex2MML - Convert itex equations to MathML

SYNOPSIS
     use MathML::itex2MML;
 
     $text    = 'This is an inline equation: $\sin(\pi/2)=1$.';
 
     # convert embedded itex equations to MathML:
     $converted = itex_html_filter($text);    # This is an inline equation: <math xmlns='http://www.w3.org/1998/Math/MathML' display='inline'><semantics><mrow><mi>sin</mi><mo stretchy="false">(</mo><mi>&pi;</mi><mo stretchy="false">/</mo><mn>2</mn><mo stretchy="false">)</mo><mo>=</mo><mn>1</mn></mrow><annotation encoding='application/x-tex'>\sin(\pi/2)=1</annotation></semantics></math>.

     # just the equations:

     $text    = '\sin(\pi/2)=1';

     # inline equation (without the $'s)

DESCRIPTION
    MathML::itex2MML converts itex (a dialect of LaTeX) equations into
    MathML. Inline equations are demarcated by $..$ or \(...\). Display
    equations are demarcated by $$...$$ or \[...\]. The syntax supported
    is described at https://golem.ph.utexas.edu/~distler/blog/itex2MMLcommands.html .

    It is strongly suggested that you run the output through MathML::Entities,
    to convert named entities into either numeric character references or UTF-8 characters,
    if you intend putting the result on the Web.

    MathML::itex2MML is based on the commandline converter, itex2MML.

FUNCTIONS
    The following functions are exported by default.

    * itex_html_filter
        Converts the equations, passing the rest of the text through, unchanged.

    * itex_filter
        Outputs just the converted equations.

    * itex_inline_filter
        Converts an inline equation (without the $'s).

    * itex_block_filter
        Converts a block equation (without the $$'s)

INSTALLATION ON UNIX
