xml_spellcheck - spellcheck XML files

=head1 SYNOPSIS

  xml_spellcheck [options] <files>

=head1 DESCRIPTION

xml_spellcheck lets you spell check the content of an XML file.
It extracts the text (the content of elements and optionally of
attributes), call a spell checker on it and then recreates the
XML document.

Note that all options can be abbreviated to the first letter

=over 4

Gets the options from a configuration file. NOT IMPLEMENTED YET.

=item --spellchecker <spellchecker>

The command to use for spell checking, including any option

By default C<aspell -c> is used

=item --backup-extension <extension>

By default the original file is saved with a C<.bak> extension. This option
changes the extension

=item --attributes 

Spell check attribute content. By default attribute values are NOT
spell checked. NOT YET IMPLEMENTED

=item --exclude_elements <list_of_excluded_elements>

A list of elements that should not be spell checked

=item --include_elements <list_of_included_elements>

A list of elements that should be spell checked (by default all elements
are spell checked). 

C<--exclude_elements> and C<--include_elements> are mutually exclusive

=item --pretty_print <optional_pretty_print_style>

A pretty print style for the document, as defined in XML::Twig. If
the option is provided without a value then the C<indented> style is
used

=item --version
