=head1 NAME

Any::Template::Backend::Text::MicroMason - Any::Template backend for Text::MicroMason

=head1 SYNOPSIS

	use Any::Template;
	my $template = new Any::Template(
		Backend => 'Text::MicroMason',
		Options => {
			Attributes => {global_vars => 1},      #MicroMason %attribs
			Mixins => [qw(-HTMLTemplate -Filters)] #Specify mixins
		},
		File => 'page.tmpl'
	);	
	my $output = $template->process($data);

=head1 DESCRIPTION

Attributes may be passed to Text::MicroMason in the {Options}{Attributes} key.  
The {Options}{Mixins} key is used to pass mixins to Text::MicroMason.  

Inputs from a file and string are provided natively by Text::MicroMason.
Input from a filehandle uses the default implementation (which is to read into a string).

Output to filehandle is based on the default implementation of capturing output in a string and writing
this to a filehandle, so watch out for this if your output is very large.  Output to a file uses the native
Text::MicroMason implementation.

Output to a coderef uses the default implementation of buffering all the output in a string and passing this to a coderef,
so again beware of the memory consumption if the output is large.
