 451 #               Variables will only be changed if they have not yet been
 452 #               specified.
 453 #
 454 # libname <string> - Set libname to <string>. This is the name of the

 456 #               It will show up in the version string, too.

 458 #               the AROS-LHx macros in the location part (last parameter)
 459 #               and to specify defaults for libbase and libbasetype

 462 #               xXxBase.
 463 # libbase <string> - Defines the name of the library base (ie. SysBase,
 464 #               DOSBase, IconBase, etc). If libbasetype is not set, then
 465 #               it is set to <string>, too.
 466 # libbasetype <string> - The type of libbase (with struct), ie.
 467 #               struct ExecBase, struct DosLibrary, struct IconBase, etc).
 468 # libbasetypeptr <string> - Type of a pointer to the libbase. (eg.
 469 #               struct ExecBase *).
 470 # version <version>.<revision> - Specifies the version and revision of the
 471 #               library. 41.0103 means version 41 and revision 103.
 472 # copyright <string> - Copyright string.
 473 # define <string> - The define to use to protect the resulting file
 474 #               against double inclusion (ie. #ifndef <string>...)
 475 #               The default is _LIBDEFS_H.
 476 # type <string> - What kind of library is this ? Valid values
 477 #               for <string> are: device, library, resource and hidd.
 478 # option <string>... - Specify an option. Valid values for <string> are:
 479 #
 480 #                   noexpunge - Once the lib/dev is loaded, it can't be
 481 #                               removed from memory. Be careful with this
 482 #                               option.
 483 #                   rom - For ROM based libraries. Implies noexpunge and
 484 #                               unique.
 485 #                   unique - Generate unique names for all external
 486 #                               symbols.
 487 #                   nolibheader - We don't want to use the LibHeader prefixed
 488 #                               functions in the function table.
 489 #                   hasrt - This library has resource tracking.
 490 #
 491 #               You can specify more than one option in a config file and
 492 #               more than one option per option line. Separate options by
 493 #               space.
