# [+nowrap+] If set to True, don't wrap the output at all, not
# even inside a <tt><pre></tt> tag (default: false).
# [+cssclass+] CSS class for the wrapping <tt><div></tt> tag
# (default: 'highlight').
# [+linenos+] If set to 'table', output line numbers as a table
# with two cells, one containing the line numbers,
# the other the whole code. This is copy paste friendly,
# but may cause alignment problems with some browsers
# or fonts. If set to 'inline', the line numbers will
# be integrated in the <tt><pre></tt> tag that contains
# the code (default: nil).
# [+linenostart+] The line number for the first line (default: 1).
# [+lineanchors+] If set to true the formatter will wrap each output
# line in an anchor tag with a name of L-linenumber.
# This allows easy linking to certain lines
# (default: false).
# [+lineanchorsid+] If lineanchors is true the name of the anchors can
# be changed with lineanchorsid to e.g. foo-linenumber
# (default: 'L').
# [+anchorlinenos+] If set to true, will wrap line numbers in <tt><a></tt>
# tags. Used in combination with linenos and lineanchors
# (default: false).
# [+inline_theme+] Inline CSS styles for the <pre> tag (default: false).
