-- Verbatim class
-- Represents a line translated directed to the binding file.
-- The following filds are stored:
--   line = line text
classVerbatim = {
    line = '',
    cond = nil,    -- condition: where to generate the code (s=suport, r=register)
}
classVerbatim.__index = classVerbatim
setmetatable(classVerbatim,classFeature)

-- preamble verbatim
function classVerbatim:preamble ()
    if self.cond == '' then
        write(self.line)
    end
end

-- support code
function classVerbatim:supcode ()
    if strfind(self.cond,'s') then
        write(self.line)
        write('\n')
    end
end

-- register code
function classVerbatim:register (pre)
    if strfind(self.cond,'r') then
        write(self.line)
    end
end


-- Print method
function classVerbatim:print (ident,close)
    print(ident.."Verbatim{")
    print(ident.." line = '"..self.line.."',")
    print(ident.."}"..close)

-- Constructor
-- Expects a string representing the text line
function Verbatim (l,cond)
