-- - None: Library Project Files are not supported at all
-- - Static_Only: Library Project Files are only supported for static

-- - Full: Library Project Files are supported for static and dynamic

function Support_For_Libraries return Library_Support;
-- Indicates how building libraries by gnatmake is supported by the GNAT
-- implementation for the platform.
function Standalone_Library_Auto_Init_Is_Supported return Boolean;
-- Indicates if when building a dynamic Standalone Library,
-- automatic initialization is supported. If it is, then it is the default,
-- unless attribute Library_Auto_Init has the value "false".
function Archive_Builder return String;
-- Returns the name of the archive builder program, usually "ar"
function Archive_Builder_Options return String_List_Access;
-- A list of options to invoke the Archive_Builder, usually "cr" for "ar"
function Archive_Indexer return String;
-- Returns the name of the program, if any, that generates an index to the

-- On Unix, returns "o".

-- System dependent dynamic library extension, without leading dot.

-- Build a dynamic/relocatable library
--
-- Ofiles is the list of all object files in the library
--
-- Foreign is the list of non Ada object files (also included in Ofiles)
--
-- Afiles is the list of ALI files for the Ada object files
--
-- Options and Options_2 are lists of options to be passed to the tool
-- (gcc or other) that effectively builds the dynamic library. Options
-- are passed before the object files, Options_2 are passed after the
-- object files.
--
-- Interfaces is the list of ALI files for the interfaces of a SAL.
-- It is empty if the library is not a SAL.
--
-- Lib_Filename is the name of the library, without any prefix or
-- extension. For example, on Unix, if Lib_Filename is "toto", the
-- name of the library file will be "libtoto.so".
--
-- Lib_Dir is the directory path where the library will be located
--
-- For OSes that support symbolic links, Lib_Version, if non null,
-- is the actual file name of the library. For example on Unix, if
-- Lib_Filename is "toto" and Lib_Version is "libtoto.so.2.1",
-- "libtoto.so" will be a symbolic link to "libtoto.so.2.1" which
-- will be the actual library file.
--
-- Symbol_Data is used for some patforms, including VMS, to generate
-- the symbols to be exported by the library.
--
-- Note: Depending on the OS, some of the parameters may not be taken
-- into account. For example, on Linux, Foreign, Afiles Lib_Address and
-- Relocatable are ignored.

-- Returns the file name of the library file of a library project.
-- This function can only be called for library projects.
