| -- - None: Library Project Files are not supported at all |

| -- (gcc or other) that effectively builds the dynamic library. Options |

| -- 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. |
