-- Increment is the number of spaces for each indentation level

-- W_Char, W_Eol and W_Str can be used to change the default output
-- procedures. The default values force the output to Standard_Output.
--
-- If Eliminate_Empty_Case_Constructions is True, then case constructions
-- and case items that do not include any declarations will not be output.
--
-- If Minimize_Empty_Lines is True, empty lines will be output only after
-- the last with clause, after the line declaring the project name, after
-- the last declarative item of the project and before each package
-- declaration. Otherwise, more empty lines are output.
--
-- If Backward_Compatibility is True, then new attributes (Spec,
-- Spec_Suffix, Body, Body_Suffix) will be replaced by obsolete ones
-- (Specification, Specification_Suffix, Implementation,
-- Implementation_Suffix).

-- Id is used to compute the display name of the project including its
-- proper casing.
